Is go daddy really pitching a shopping cart that can not combine shipping? Please confirm so I can Cancel my subscription if this is the case.
I'm confused by your statement of "combine shipping"
I did a sample product with a flat rate shipping of $5 and a 2nd of USPS
If I have just the USPS $20.90 - If I add the product with flat rate it's $25.90 so this is working as I would expect.
