I had a situation a couple of years back from a guy who had purchased some collector's edition action figures that I wanted to get rid of. He did pay top dollar only because in that particular collector's market, they were listed as such in several difference magazines, etc... Granted I only paid a couple of bucks when I originally purchased them but it was his choice to get involved in a bidding war for them.
Anyway, I packed them in bubble wrap and covered them in styrofoam peanuts and securely taped the entire box. Given how much he paid, I did NOT want anything to happen to them. I event sent them express with insurance and I covered the extra cost.
What does this guy do? He emails me complaining that the items were open and he was angry that I would sell something "mint" when they weren't. I was stunned. I never opened them ever. And said so. He argued. I sent him an email back stating that I wasn't going to give him a refund unless he shipped them back to me EXACTLY in the same manner, i.e. insurance and express. He refused, said he didn't ask me to do that so he didn't have to (he was right).
I still insisted he mail them back. He wanted to be reimbursed the cost of the items, the cost of the original shipping and the cost to ship them back BEFORE he mailed them. Now I knew something was up.
I told him I wouldn't provide any refund of the shipping cost, only the cost of the item. He stated that whenever he bought ANYTHING from any major service, i.e.
Walmart, catalogs, etc... and he returned it, he ALWAYS got reimbursed for all shipping both ways, plus the cost of the item. And those companies would usually throw in a gift card or something else to satisfy his anger. So he said I should do the same for him and add on a few bucks to the refund for his trouble.
Plain and simple, the guy was a scam artist and a liar. I told him so, wished him well, and invited him to post a negative. I said I would do the same to him. He never posted anything, and I never heard from him ever again. I still posted a negative on his profile though to forwarn other sellers.
