I need to be able to set shipping options per product. For example, a small item can be shipped via USPS, Fedex, or UPS. A medium can be shipped via UPS or Fedex. A large item can only be picked up in store. How can I make it so that upon checkout, only the available shipping items for each product appear?
With the way cs-cart multi vendor is set up, I can only set shipping based on the vendor, not the product.
