Over selling is not intentional stores don't benefit from upsetting customers. Call the stores and see if they have your item in stock, online stores vs brick stores often have different availability. You may need to call multiple locations. If you want the item that bad do the work to get it. This review won't make the website restock.
Probably the website wasn't updated when the item was ordered and could have been already out of stock when you ordered the item. I had the same issue with Saks Fifth Avenue website on a handbag.
