Autotech USA Online Wholesale Parts Store Inferior parts sold as 'lifetime warranty' that they do not honor, Florida

I bought a set of spark plug wires for my old Mercedes from onlinewholesaleparts on ebay.  Got the part in, installed it, and within a week, the wires literally started falling apart.  Sent an email, got a response saying I had to pay $10 for shipping plus return my old wires or buy a new set and have them refunded less shipping.  So I get the second set of wires, and the same thing happens, just took a little longer.  

This all happened between January and July 2012.  Sent another email requesting a refund, as I had purchased a set of wires locally because I couldn't wait a week to get a new set from these guys.  After multiple emails, I am told that I am not eligible for a refund because the 30-day refund period had passed.  Absolute junk, stay away from their parts!
