I don't see the facebook link, it sounds like a good idea, I would like to check it out...
I have been screwed a few times on ebay, both sides of the fence though, as a seller you are going to get fucked once and a while, with the new rules as a buyer you can not lose.
I had a few service manuals listed to cars I no longer own and will never own again, my manual shelf was too full and I started putting some on the floor so I figured time to clean through some and turn them into money. So I get a 'best offer" on one (of course it was a cutlass, I could picture the buyer and his leather jacket with zippers on the sleeves, lol), the book was listed at $40 (half of the lowest one I found on ebay), he offered $5, lol.. So I declined and countered with $30, he emailed me saying it was used and only worth $5 and he wont pay more than that, and he will buy another one locally for $10, and some other BS.. I replied that the shipping will cost more than $5 and I would rather keep it than pay to get rid of it...
So someone uses buy it now with no offer in the mean time and its sold, he emails me pissed off sayng I took too long, and screwed him... Then he buys 2 of my auctions, large items, a compressor pump and a 2x4 sbc intake manifold... I was a bit confused but sent them, shipping was something like $165.
About 2 weeks later i get 2 negatives and ebay emails me to tell me I have to take the items back, I was charged $209 to ship them back to me, and they refunded him the complete total including the shipping charges!!! So he screwed me over $350 just in shipping!!! He did this in spite, he didn't need them parts, he did it to screw me, he knew ebay would side with him if he said they were not as described and he didn't want them. The intake came back with a corner smashed off of it and the compressor had the mounting taps all knocked off of it... SO that one douche cost me a $320 compressor a $200 intake and $350+ in shipping, almost $1000!!! I saved his name and address, some day if the doctors ever tell me I have 30 days left, that ************* has 29, that list is actually a couple pages long now, I'll have a notebook full if I live a lot longer, lol...
