I just bought 2 cards on eBay. 1988 Donruss and Fleer cards of Gregg Jefferies. The purchase set me back a whopping $2.18 , tax included. The problem is, I might already have both of those cards in my collection. I wasn't completely sure, though, and was too lazy to look through my collection to see If I did, indeed, already have them. Oh well. Worst case I'll now have doubles of a couple of cards that I hold In high esteem.
