Adding product to cart after each line?
I am developing a POS system for our retail store we are opening soon.
I want to use the same eCart system we have for our web site.
I'm having a custom javascript/ajax solution built to autofill product details from the database.
Does it make more sense to add each line to the cart when the next line is started through a javascript function or at the end when all of the items have been entered.
If after the form is submitted, would add the line items from the form to the cart?
