I am doing an e-commerce cart.
In the past, I would have the cart saved in session. So the cart is destroyed when the session is terminated.
But I saw zen cart and other system using the permanent cart now.
Using the permanent cart is good for the sale I think. But add a little confustion, say the shopper didn't log in yet, but he add some thing to his current cart, then he logged in, he also has something in his permanent cart.
Do I merge these two carts together? Will the shopper feel inconvience if we merge his old cart to the new cart? he may not need the old cart.
We already has wish list, is this more like the permanent cart?
So what do you think, make the cart session or make the cart permanent?
Thanks!
