I have an oscommerce store which has the qtpro contribution intalled (this allows you to keep track of stock of product attributes i.e. it allows you to keep track of the numbers of specifically sized nike air trainers rather than just nike air trainers in general).
I have recently set up an eBay shop. I would like my eBay listing to end when a product runs out of stock in my oscommerce store. Also, if possible, I would like my oscommerce stock to decrease when a product is sold on eBay. It would also be helpful if eBay listings would restart when new stock is bought.
