Totalsports black friday fail

I purchased a football jersey that was on special, online from totalsports on the 22nd. Everything went well, paid for the purchase and received an confirmation email and invoice. Fast forward 3 days later, I receive an email telling me that my order has been canceled. Apparently there was a problem with their system and the jersey had been sold out but was still listed as available. The issue now is that they say they will refund me my money and I'll have to buy the jersey at full price as the sale has passed. Now I as their customer who purchased the product while the sale was on, listed as available, paid for it and on top of that received confirmation of the purchase, am feeling aggrieved. Since I now can't purchase it anywhere else on special since the sales have now passed. On top of them making a **** up my order, they've also ****** me of the opportunity to buy it somewhere else during the black friday sale.
