My question would be why would it cost more to send it back? Not even a little more but almost 2.5 times more? Something isn't right.
Unless:
A. Whitepunk gets a discount on shipping parts (in which case he should just pay for the shipping label and email it to Hemi to affix to his package)
or
B. Hemi isn't using the same carrier. (there can be quite the difference in USPS vs Fedex or UPS
In my opinion, if white is offering to take it back and pay for shipping, he is doing more than enough to make a buyer happy.
