Accidentally bought my own card beck from the shop

I know this is gonna sound pretty darn Bush leauge but earlier I was in a hurry and accidently bou GJ ht my own card back when flipping instead of opening up a new buy order,when all was said and done I had no funds returned from the sale and no card returned is their someone I can notify about this? I totally blame my wife for not getting how much more important and rushing me not the show itself but I'd still like my money and card back.

Think you just got to chalk it up as an accidental loss. Think we have all been there. Just got to hope they are on the smaller orders. Usually they are because we go fast on those.
