SWFA has this situation a lot (and not just during their sales). Not that difficult to tie their inventory in with their website orders. That way when they're out of inventory, it's reflected on their online order page, and it can't be added to checkout and tie up your CC balance.
This has been my biggest beef with these guys. Seriously SWFA, step into the 21st Century and get an up to date automated inventory system. I don't mind backordering something if I KNOW it's going to be backordered. What I DON'T like is having my CC charge for something that is NOT in stock and NO IDEA when it will be in stock.
This is my first time ordering from this company and I'm not happy they excepted my money knowing the item wasn't in stock without informing me up front before placing the order.
A Doe walks out of the woods today and says, that is the last time I'm going to do that for Two Bucks.
