Very cool, I expect many companies would just keep the money. I'm in Missouri, and the check was about 10% of my original DM pledge. That's an extra deck at my FLGS this weekend.
One of the lesser perks of going to Vault Tour, is that they say all participating decks will get a "Contender" accolade. How long will it take for that to be applied to decks? Even though I didn't do especially well, I might splurge on a deck clone anyway.
(Random aside: Since GG provided all the decks for Sealed, all unwrapped and in their own sealed packaging, did they pre-scan those decks, and will they be eligible for the Contender accolade too?)
