I am trying to create using a small sales tool like that of amazon(ie shopping
cart, checkout).
1)Just wondered if there is already a interface for this already.
2)Also how do i go about creating the actual money transactions? Do I use
paypall.
3)How do you prevent double purchasing-eg one product in stock-user1 is the
first to put it in cart but continues to shop. User2 comes along and puts same
product in cart but goes to checkout quicker.
I know you could edit the stock level as soon as a product is added to a
cart. But really technically the product is not sold until confirmation in
checkout. And the user may not even buy.
