Isn't that fee like $2? Is it even worth trying to get that back?
$3? Maybe, maybe not. Another $3 on the refund transaction (not sure if that will be the case or not)? I think so. I wouldn't be spending the rest of my week on the task, but I'll certainly be firing off an unpleasant email that they can respond to or ignore. It's all relative, but I don't generally relish the idea of just throwing money away, period.
Aside from the fact that any business generally wants to avoid refunds (they're already eating $3 on the transaction), this is why you don't generally charge a customer before you have the item.
They actually wrote me an email that said to check back because they were working to get the item. Yeah, I will definitely pay yet another fee to maybe buy it.
