He/she doesn’t seem to have a good grasp of the English language...similar to other scam messages I have seen.
Don’t do it!
About six months ago I sold 4 iPhone 5s on eBay and scammers tried to get me on two separate sales, eBay buyer protection policy also sucks! Here is the details:
1) First auction was bid up beyond a normal price. The winner had a great rating but I thought something was up. Despite having good reviews (eBay no longer allows seller to give buyers bad reviews) the comments told a different story. This guy generates false papal statements indicating he paid hoping you ship the phone.
2) Next auction was won by a foreigner in another country despite my auction stating US sales only. He insisted I ship him the phone, but I canceled and never invoiced. eBay told me to relist and the guy kept bidding again, so eBay told me how to block him.
3) On another phone the winner claimed poor battery life and asked for a $40 refund. He informed me how under eBay’s buyer protection program he can claim a defective product, get his money back and keep the item. I looked into this and there are many stories supporting this claim.
In the end I sold the four phones and was made more then Verizon would have given me. I felt uncomfortable during all the auctions and watched my back constantly. If I choose to do this again I’ll try Amazon, done with eBay as a seller.
