Yeah that's probably where most of my UPC's I used for anything the past year came from... I ordered most of my stuff before a ton of things I wanted on Vintage or CW 2011 cards were out.
I cut one UPC out from a blue card, then I remembered that I keep all the inserts to all the figures I opened in the last 10 years or so and the UPC is attached.
Did some digging through the mountain of inserts and cards, low and behold I found at least 10 of them I opened already (though 1 was the unqualified 501st Walmart Clone Jayson mentioned - thanks again)
I had enough for 2 Sgt. Bric's. Sent them off today (fingers crossed)
