I have a site which sells limited quantities of limited editions...we pre-announce our time of listing so we get quite a rush to buy....and we are constantly getting overselling. We use products with attributes stock add-on. Is there any way to stop this, either a mod or code change, to change how the cart keeps track of stock. All admin settings are set to not allow overselling....I also have an additional bit of code in the main ipn handler to check for stock with attributes.. see this thread...still not helping at all...today we put 32 items on the site, in 6 different sizes, and some sizes were showing -7!!!

What we actually need is what 'Big Commerce' offers....that is, a system where products entered into somebody's cart are deducted from the stock total there and then, rather than when the person hits the confirm transaction button to make the sale final. Big Commerce has a setup, so that if the cart item is not bought within a pre-definable time, the stock is returned to the site as available, and that cart emptied.

If anyone knows of a way to make/modiify zen cart to do this, I would be most grateful.....otherwise I will have to look elsewhere, and go through the whole site setup thing again....big groan!
