Amazon.sucks!

Hi,
I'm actually looking for some help. I'm having trouble with Amazon.com trying to charge me almost $200 for shipping on some weights that are supposed to be shipped for free ... the particular items are the 50 and 100 lb solid hex dumbbells from Champion. They are shipped from eSportsonline, and there is a little logo that says ship free ... free shipping on purchases over $50. The amazon e-mail people (what kind of crappy system is that?) weren't helpful. I understand that such a system allows people to, probably, work more efficiently, but if they don't give you the information you need, that doesn't really help much. Anyway, amazon says super saver shipping doesn't apply because it's shipped from a 3rd party, which is understandable, but they say I have to pay $170+ in shipping ... no thanks. Now, this might not be, but I'm not going to risk putting the transaction through, hoping that the shipping is free.
Can anyone help me out on this?
Evan
