I am looking for a shopping cart that is free or VERY cheap. I need one that allows you to add options like color or size and I need to having a shipping calculator for USPS that goes by weight. Do any of you know of one? I DO NOT want to use Zen or Ecommerce
You can use virtuemart. For people who are using zen styled shopping cart this is very good. And there are also other news circulating market that Google Checkout support has been withdrawn for Zen Cart. It is not advised to use the module as it is incompatible with various shipping modules amongst other problems.
