Hi again
Thanks on your answer; I will try to explain my self better
We sell unique items it's mean that we don’t have from the same items two… so when the customer want to buy items he/she need to fulfill request order form, in this form the customer request the wanted items, the purchase doesn't done immediately via the site!!!
Now our customers write in the order form the codes of the wanted items, what we want is to save this and to give the customer the option to collect items by adding to the cart and to arrive to the order form with the list of items
So what we actually need is simple cart that collecting items and arrive to request order form
We check all the E-Commerce carts and all of them are immediately payment
We don’t need security because the payment doesn't do via the site.
Thanks again.
