RE: beware grayson hobby
I had a problem with a well known web automotive parts supplier. There are various "versions" and prices of a common part.
I ordered a specific version, was charged for it, and received a less expensive version, which was somewhat defective, but usable.
When I contacted them, I sort of got the runaround. (multiple times, multiple call centers.)
The part appeared to have been sent from the OEM's warehouse about 90 miles away.
Finally, to make a long story short, I ended up calling my credit card company.
This time, the parts supplier ended up in a 3 way call with me and the CC company.
The threat of charge back did make a big difference. When all was said and done, I still ended up eating the ship back cost of the defective and mis-billed part.
The OEM warehouse had packaged the part for internal delivery, and apart from the billing question, this was the start of the problem. (Small box, no packing, heavy part.)
