You can get that exact part, 52079880AA, from Rock auto under $10.
And does Rock Auto ship for free? Odds are it will be more then the ebay one once you add shipping.
So, what you are saying is that the "free shipping" claim is fraudulent and is baked into the the asking price. I don't pay for fraudulent claims, so I won't buy from someone that inflates the price 50% and claims "free shipping".
For the record, from RA with shipping to me is still $2 cheaper than your "free shipping" ebay scammer.
And this genuine Mopar part is even cheaper than RA, with free shipping
