I don't think "vintage cards" are mentioned anywhere on any sell sheets I've seen, so I'm wondering if you get something for every code, or if you sometimes just get "virtual coins". Last year even if you got a 1992 Topps Bill Doran it was at least something, ha.
If they still sell well I think I'll just sell them this year instead of trying to trade or redeem them. It seems like even though they were selling all year for $2-3 whenever I offered them for trade nobody wanted to give me a fair BV in return (if something is selling for that price I'd consider the "BV" to be at least $5). I redeemed around 20 of them and while I did at least get one die-cut and traded it for one I needed, and it was fun trading the other cards, when they day was done I got waaaaaaaaay less shipped to me than the $50 I could have sold the codes for.
