Just thought I'd share a little "buyer beware" story that just cost me about $100:
Performance Products recently ran a sale where if you purchased a new AC compressor they included a new drier and expansion valve at no charge. Okay, not such a bad deal to get everything at one place plus there were some other things they had good prices on that I wanted for a few of the diesels. The car needing the compressor in the new '78 and it had been converted to an r134a breathing Sandin rotoary. So the sale page on Performance Products site had three pictures, a Sanden, York and R4. I chose the Sanden and placed the order. So the Big Brown Truck comes and I go through the package and find not a Sanden that I ordered but a York. Well, I then tried to navigate Performance Products labrythine voice prompt system and after about five minutes ended up with a sales person. I asked for "customer service" and he explained they didn't really have a customer service department, even though there's a number on the invoice and pretty catalog, but that he could help me. So I explained the issue and he gave me an return number for the York to ship back, at my expense, and that a Sanden would be right out to me again at my shipping expense. Well, it showed up yesterday and turned out to be an R4. So, back through the voice prompt system (only two minutes this time until encountering a human) and again related my dilemma, this time to be informed they don't even carry Sanden compressors. But I got a return number to ship back the R4, of course at my expense.
So now I've got to wait for about $600 dollars to be credited to my card from these highly efficient and motivated individuals and eat the shipping charges both ways. Oh, and for the Sanden? Got a brand new one from eBay with a 1 year warranty for $125.
Learned my lesson!
