Honestly think most experts including Dan thought there was less than 1% chance of it shipping out. Yet many times the store will give out gift cards out of good will making it worth it to buy a price mistake even if you know you'll never get the item. I don't think there's much wrong with that.
"Hi, ordered what I knew was a mistake and didn't think I would receive the item but was hoping to get you to give me a gift card to make you pay for your mistake since I am not getting the item I never thought I would get. Now that I got the item which I shouldn't have gotten I want to give it back to you."
I wonder if anyone got a gift card from them for a cancelled order which they ended up receiving.
