In the same plaza as my local Wal-Mart there is a Dollar Tree. They often have packs of cards. Recent years, a variety of sports, mostly with five cards per pack. This time they had the Ultimate Jumbo Pack. 30 cards for a dollar. Mostly junk wax. And a lot of Marlins. I picked up two packs.
Here are two decent cards from the packs.
Mark Fidrych (card # 462)
Ron Guidry (card # 548)
I've tossed them up on Listia, if anyone is interested.
