My local is a great place to pick up non-"hits" from high-end card sets, as you've probably figured out. The gamblers in the area will open this stuff and basically throw it out when they're done, sometimes even the numbered stuff. So, this wonderful green Mays, numbered 38/75, is mine now, for less than what I'd have paid for a pack of gum. Tribute scans surprisingly well for being as shiny and reflective as it is, don't you think?
I love getting cards I'd have no way in hell of getting access to if it weren't for pack ripping-as-gambling. Sadly, someone beat me to the 40 or so more Inception base cards they had sitting there this week, left behind by the person who went nutzoid on that product, but hey, you can't win 'em all.
