I'm surprised that no one buys at Ebay. In the last 5 years, when comparing Amazon to Ebay, I always found the same part cheaper on Ebay. There are some search tricks, I've found to get to the very lowest price, for the same item.
I bid on somethings and get it very cheap but, most everything I buy, is "Buy it now, with free shipping". Ebay has it's problems but, 99% of the time, you will have your seller problems, resolved in your favor and your money is secure. You won't get stuck with paying and not getting what you bought or a refund.
