Need some help and hoping someone has an answer, and I am fairly new to zen-cart.

Almost all of my shipping will be weight based and determined by the carriers (UPS, USPS, and FedEx) and there is no free shipping --- except for 1 or two items -- whichis were i need help. This items also will need to be dropped shipped, but the company that does the drop shipping is offering free drop shipping, so I want to pass that onto the customer. They only ship UPS, yet all the products on my website can be shipped by the customer choice (UPS, FedEx, or USPS)

Our website is http://www.thegardenpet.com if you need to look at what I am doing.

We are using version 1.3.7 and have installed a custom template bought of the template monster, and the have added the cross sell and advanced cross sell module.

Any help would be greatly apppreciated, Thank You.

Robert
