I have an x-cart website (v4.4.5) with Smart Template, where every item has a stock of 1. I'm looking for an x-cart module where I can set the stock to 0 when someone adds the item to their cart rather than at checkout. I then want to allow the item to remain in the cart for a configurable amount of time, eg. 7 days. Then if not checked out, expire the item out of the cart, resetting the stock to 1. Further, I would like a configurable option to prevent the customer from re-adding the item back into their cart after it expired.
