Customers are able to buy out-of-stock items?

How is this happening?  I have tried to duplicate the problem, but I cannot add the product to my cart.  How are my customers adding the product to their cart?  I have all the fields marked correctly:  "0" stock, do not allow backordering, etc.  Following is an out-of-stock item:  http://www.thesleepshop.com/store/pc/Queen-Bed-Bridge-Support-System-Deluxe-Model-51p79.htm.  Any ideas??  Thanks! 

ProductCart validates both scenarios (add to cart from Wish List and "repeat order") to check for product availability.

Katharina: which version are you using? These features have been around for a while, if we remember correctly.

Same for me, 3.11a.  Haven't noticed the problem lately, so I'm not sure if it still exists.  We still get occasionally orders on out of stock item, and we can't figure out why.  Its rather seldom.  Had one yesterday.  I know it did not come from a repeat order or wish list, since I know this customer.  Just can't recreate it so we simply adjust the invoice and end of it.  We sell a lot of little craft items, so it is not an issue to adjust a little.  Harder with big items like yours.

I have had a couple of instances where PC did not properly adjust inventory counts after a purchase. In one case I had 2 pieces of an item left in stock and a customer a few hours later did purchase the last two pieces. Evidently the inventory was not properly adjusted as another customer purchased 2 pieces of the same now out of stock item and low and behold, the count was readjusted to zero and did come up as out of stock (after customer no. 2  "purchased" the items).
