How did the other group orders go with the shipping amounts?
What difference did you get between the quoted/paid amount and the actual amount on the box?

I was quoted/paid - US$165.25
The actual - US$109.10
Difference overcharged - US$56.15

Add to that, my last group order being overcharged - US$73.29
That's US$129.44 extra paid from just two orders... imagine how much extra they are making from every order.
