I want to make sure I am not the only one with this issue.
If you have items in your store that are exempt from shipping and add them to your cart, and then you add an item that requires shipping, the UPS module seems to take into account the weight of the exempt items when it calculates it.
Product A weight 10lbs and is free shipping
Product B weights 1lb and requires shipping
With just Product B in your cart the shipping is $11
With Product B and A in the cart the shipping price goes up
This is really noticeable when you add like 20 of product A and still have only 1 of product B, then get a quote.
Is it just me and I have something configured wrong, or is this a bug?
