One feature of the Priceline hotel bidding process is that you can continue bidding at the same quality level if you exit the Priceline website after each bid rejection and then re-enter the website and make some change to your zone selection configuration.

This feature permits permutations bidding in which you can maximize your bidding opportunities by using all zone combinations available when including Acceptable Zones (zones where you want to stay) and Free Re-bid Zones (unwanted zones that are "safe" because they have only hotels rated lower than at the level at which you are bidding).

Below are 13 matrices that are adaptable to various bidding situations that you might encounter.

The first five matrices are designed initially for use with one Acceptable Zone with increasing numbers of Free Re-bid Zones:
One Acceptable Zone / Two Free Re-bid Zones
One Acceptable Zone / Three Free Re-bid Zones
One Acceptable Zone / Four Free Re-bid Zones
One Acceptable Zone / Five Free Re-bid Zones
One Acceptable Zone / Six Free Re-bid Zones


If you have more than one Acceptable Zone, you have a choice of going two bidding routes:

If you want to bid all of your Acceptable Zone simultaneously, you can adapt any of the five matrices noted above by designating your Acceptable Zones as A/1, A/2, A/3, etc. and substituting the combinations for each "A" designation in a matrix.
or
If you are willing to alternate or rotate your Acceptable Zones, you may be able to use one of the following eight matrices, designed to further enhance your number of bidding opportunities:
Two Acceptable Zones / One Free Re-bid Zone
Two Acceptable Zones / Two Free Re-bid Zones
Two Acceptable Zones / Three Free Re-bid Zones
Three Acceptable Zones / No Free Re-bid Zones
Three Acceptable Zones / One Free Re-bid Zone
Three Acceptable Zones / Two Free Re-bid Zones
Four Acceptable Zones / No Free Re-bid Zones
Five Acceptable Zones / No Free Re-bid Zones

Newcomers to BiddingForTravel (BFT) should carefully read all of the 31 topics covered in the Hotel / Frequently Asked Questions (FAQs) before using these permutations matrices to bid on Priceline.

Here's the BFT Hotel FAQs link: http://biddingfortravel.yuku.com/topic/2560


Permutation bidding is discussed extensively in these two threads:
http://biddingfortravel.yuku.com/topic/581

http://biddingfortravel.yuku.com/topic/615



Here are some other topics that you may want to review before beginning permutation bidding:

How can you tell which zones offer which hotel star levels on Priceline?

Go to the Priceline hotel zone selection page for the city where you will be bidding.

Under "Step 1" -- place a check mark in the box of the first zone as though you were going to bid that zone.

Scroll down to "Step 2" and note the available quality levels, which will be highlighted in blue for the first zone.

Then scroll back up, uncheck the first zone under "Step 1" and then check the second zone and note the quality levels offered in that zone.

Repeat this procedure for each zone listed. Make sure that only one zone is checked each time.

If a city has many Priceline zones, you might want to build a zone chart as described here:
p070.ezboard.com/Develop-...=318.topic

You should always re-check zone definitions and quality levels offered immediately prior to each bid (even if you just bid the same city on the day before) as Priceline frequently changes quality levels offered and zone definitions. When performing this check, make sure the check-in date is not the current date, or you will not be able to check the zones that do not offer same day bidding.


What is a Free Re-bid Zone?

Use of free re-bid zones in permutation bidding can greatly expand your bidding opportunities.

Free re-bidding is a technique that allows you to add a zone that you DON'T want, enabling a higher bid in the zone that you DO want---without any risk of winning a hotel in the unwanted zone. A free re-bid zone then is any unwanted zone in which all hotels are rated at a star level lower than the level at which you are bidding.

For example, if you are bidding for a 2.5* hotel in your desired zone, you can safely add to re-bids any or all unwanted zones that only have 2* and 1* hotels.

If, however, you add an unwanted zone with any hotels rated at 2.5*, you risk being awarded a 2.5* hotel in the unwanted zone. If you add an unwanted zone with no 2.5* hotels, but with hotels rated at 3* or higher, you also run the risk of being upgraded to a higher-rated hotel in the unwanted zone.

Free Re-bid Zones are explained in more detail in Topics #9 and #10 of the BFT Hotel FAQs.

What should you do if you receive a Priceline counteroffer to raise your bid by a certain amount?

You should reject the counteroffer unless you have no free re-bids available and can't wait 24 hours to begin a new bidding cycle.

Counteroffers are a Priceline marketing tool designed to get customers to bid higher than needed.

However, experienced Priceline bidders use counteroffers to their own advantage. That's because they know that when bidding reaches a level high enough to generate a counteroffer, Priceline generally will accept a bid that is placed at the most recent rejected amount plus about one half of the counteroffer increase suggested.

For example, say you have consecutive bids of $44 and $45 rejected. The $45 rejection comes with a Priceline counter offer suggesting that you raise your bid by $8 to $53. In this case, you would decline the counteroffer and start a new bid at $49, which probably will be accepted.

However, if you have consecutive bids of $41 and $45 that have been rejected, the Priceline computer's $8 counteroffer trigger point might be as low as $42, making the probable re-bid acceptance amount at $46.

Frequently, if you are bidding in $1 increments, the Priceline computer will increase the counteroffer amounts by $1 with each rejection. Ignore all counteroffer amounts after the first one. Increasing counteroffer amounts are simply another Priceline marketing tool to get you to bid higher.

Priceline counteroffers are explained in more detail in Topic #12 of the BFT Hotel FAQs


I keep getting grayed out zones when I try to re-bid. What am I doing wrong?

You must exit the Priceline website after each bid rejection before re-bidding.

If you have started your bidding through www.amazing-bargains.com/priceline.html (A-B), just tap the back arrow on your browser after each Priceline rejection until you see the A-B screen with your destination city, check-in and check-out dates and number of rooms displayed. When you see this screen, just hit the forward arrow on your browser to re-enter the Priceline website and resume bidding. This process will give you a fresh screen without grayed-out zones.

On my first try at bidding on Priceline, I attempted to use the permutations technique for hotels in Downtown Memphis. I don't understand how to enter bids for the different zones, because once I checked a zone, I couldn't UN-check it. I think that I left the site and came back, and the same zones were still checked, although I was able to change from 2 * to 3*.

I started out trying for a 2* DT, couldn't get it and added Med Center. Didn't want a 2* in any other zone.

Changed to 3* DT, added (one at a time) Med Center, Airport, Cordova, for 5 bids altogether.

How do you UN-check a zone?

You don't "uncheck" a zone; you simply start a new bid. Just keep track of your bidding as you go along.

So if you want zone A, and zones B and C are free rebids, do it this way:

Bid zone A
add zone B
Bid A + B

-start over, new bid
Bid A + C
add zone B
Bid A + B + C

Allorojane, it sounds as though you may not have completely backed out of the Priceline website. You must back your browser until you see a non-Priceline screen. (If you started your bid through www.amazing-bargains.com/priceline.html (A-B), you will need to back your browser until you see the A-B screen where you entered your destination, check-in and check-out dates and number of rooms.) If you follow this procedure, when you re-enter the Priceline website, you will get a fresh screen with no checked or grayed-out zones.

In regard to unchecking a zones on a Pricline screen, all you need to do is click on the green check-mark in the box next to the zone, and the check-mark will disappear.

When Verkuilb first presented this unique bidding method I spent the time to learn how to apply his system. It was worth it. It has saved me a significant sum of money. But I am unsure about the effect of the expansion that is outlined above. As a mathematical exercise it is remarkable. But does the increased complexity intimidate potential users? Does any bidder really want to place 10 or 20 bids at one session? Is there room for more than 5 or 6 bids in an overwhelming majority of instances? I wonder how many bidders are willing to read and absorb both the Hotel FAQ's and this expanded bidding system? Will it tend to turn people away? Everyone would agree that it is a great concept but I wonder if its complexity could be lessened by reducing the number of bid combinations and thereby increase the number of bidders willing to do the work necessary to make use of it. I don't know the answer. Maybe it doesn't matter.

rmiller774,

Your post makes many valid points, and I thank you for posting here. When providing strategies to novice bidders I wouldn't suggest such a complex method, for the reasons you mention, among others.

However, advanced bidders often enjoy the challenge of narrowing down the bid increment to the minimum possible, for entertainment value. Most bidders must consider the time investment in developing and executing a strategy, and balance that against the monetary savings. But when bidding enters the realm of entertainment, such considerations become less relevant: The ability to place dozens of offers is worthy of the time investment. In some cases the number of theoretical bids exceeds the reasonable time required to place that number of bids, before the lockout would expire.

This topic by GeoNit, and the input by others, is of interest to many users, including for the purposes of "sport bidding", and for that we are appreciative. It is NOT "required reading" for beginners. GeoNit is a long-time BFT member and certainly understands these issues. I thank you for raising your points, and hope you will continue to participate here. There is no need to delete your post--please do not.

I agree w/you, KeenWink. In the beginning, I didn't use permutation bidding anywhere to the level GeoNit articulates. But, after a couple of bids, I was VERY appreciative for his explanation/demonstraion of just how many times one can make the same bid in one sitting. It has saved me a lot of money, as well as a lot of explanation when I share/teach this site to others. GeoNit's permutation bidding may have calculus origins, but it simplifies it for this math-challenged gal. Permutation bidding is good for "sport bidding," and for making sure one gets the rock bottom price when one has to make a last-minute bid. Kudos to GeoNit, and to you KeenWink for your good-natured, faithful moderation of this site, particularly during this staffing crisis.

Keenwink: As you request, I will not delete my post above.

I agree completely with chinois51's personal comments about your actions as a Moderator. I have been a member of this Board for 7 years this month (recently felt it necessary to change my ID) and have marveled over the years at the skillful advice you have provided and at your calmness and unflappability. You were a major asset back then and are needed even more today, now that there are so few Moderators. I suspect that the space below will quickly be filled by other members wanting to add their expressions of appreciation to those of chinois and myself.

(May I delete this post?)
