a peculiar math problem...

I ordered 2 toys from Big Bad Toy Store. A 1:12 scale Ford GT Roadbot, and a Choro Q series Rodimus Prime. Total shipping was about $13.70. Shipping on JUST Rodimus would have been $7.30, JUST the Roadbot $13.70. Rodimus added no extra ship cost with the Roadbot.
BBTS listed ship weight of 1:12 Ford GT Roadbot : 7.35 pounds
+ BBTS listed ship weight of Choro Q Rodimus : 0.20 pounds
----------------------------------------------------------------
UPS listed package weight : 6.40 pounds
You can see where I have an issue... assuming BBTS charges their shipping by weight, I see more than 1 pound difference between their website listings(on each item page) and the UPS actual weight.
I may curiously poke into my order history and see how other weights compare.
