Bumchex - i guess just in general because they are few and far between here. I dont see ANY for sale retail around my way, not just series 7. I do have a local comic shop dealer that I bought up his ans7 box, still need just a few more, but working more on the getting my list of needs together. He helped me get started as i was lucky to get series 2,3,4 and a sealed flashbacks box from him (to which i did get a gold pararell
) As far as ans1, i did complete my base set, have just started posting about my missing pieces. Currently looking for the b1 and b2 from ans 1. Im fairly new at the card collecting and forum thing! I additionally started collecting the 1980 pac man, super pac man, and mrs pac man cards!
