Okay, so I've had my eye on a particular power supply. I can't believe how much I'm willing to spend on it, but between suppressing noise and the convenience of no wall-warts, I'm willing to do it. I had a gift certificate to a major retailer, and searching their site, found that they had a used version of this PS for sale. I first saw it on Thursday, and I called Friday morning to order it. At the time I ordered it, it was still showing up on their website. I spoke with a real person to order it and everything on their end appeared as though they still had the item. 30 minutes after I ordered, I got a backorder notice. Naturally, this is weird, because how can a used item be backordered, right? Later in the day I called, and they opened a ticket to look into it. They said they would get back to me within 24-48 hours, and we're just beyond that (they're open 7 days a week, I'm not sure if the weekend would affect that). So I'm planning to call tomorrow. Here's my question: if the worst case scenario is that they had sold the item before I ordered it (and system slowness/glitch allowed them to think it was still available), is it reasonable for me to ask that they simply sell me a new one at the discounted price I paid? It's not like they can guarantee when they'll get the item in (or that they ever will).
