How hard are the earlier Christmas beers to trade for? More specifically PiaPT, 2 turtle doves, and 3 French hens. I know I pick up 4 calling birds and 5 golden rings off the shelf, but the others were not on my radar. I would like to collect the set for a buddy who likes Belgian style stuff and present it next Christmas. Just not sure if ill have to trade my kidneys for the earlier ones like PiaPT. I'm not looking for BA version, just the stock ones. Cheers!
