I am not sure when this started happening. If a customer adds multiple quantities of a single item to their cart the shipping amount multiplies by the quantity. If they add an additional item to the cart shipping is calculated properly.
Example
These two products are basically the same just different colors.

If you add either one to the cart and ship to zip code 50322 you get a quote of $6.39 for ground shipping if you increase the quantity to (2) you get a quote of $12.77. If you add the other product to the cart (1 of each) the quote is $9.14 and (2 T603200 + 1 T603300) $9.45.
I am running Ubercart 1.0. All products are set up as "Customer Supplied Package" with correct weights and dimensions. The UPS module is set up to ship "All in one"
