Topps - Premier Gold 2015 (16) - 5" x 7"
If anyone is interested in collecting a particular team, I have bought all three sets.
This is because I had to pay ridiculous prices for the Man United cards on eBay and I vowed not to get stung again.
A few of you got the base, green and purple sets from me last year - so if you are interested in a particular club, pm me.
I'm not sure of the exact cost (because it depends on how much the customs charges are at this end), but suffice to say - the price I'll give you them for will be way cheaper than you'll be able to get elsewhere.
