Let's call the first one "scarf girl." I sold her a brand new scarf with the tags still on it for 99 cents plus shipping. It took her eons to pay, but she finally did and I shipped her the scarf to the address she had on file with eBay. I sent her the tracking information a few days later and that's when things got weird.
Her: Oh. I didn't want you to ship it to that address. I wanted you to use the my other address.
Me: Huh. I don't know you. That's why you provide eBay with your address.
Her: Well, the address in my PayPal account is the right address. You should have gone into my account and noticed that the two addresses are different.
Me: Why would I go into your PayPal account? eBay takes care of all that. And I don't have your PayPal password.
Her: Well, can you go into the post office and find the package and get it back?
Me: Clearly you have no concept as to how the US mail system works.
Her: I'm reporting you to eBay.
Me: Go ahead.
Final outcome: eBay refunded her the money in their dime AND she received the scarf. (Thank you tracking information.)
Moral of the story: Sometimes stupid people win.
The next gem we'll call Jacket Girl. Jacket Girl bought a worn once jacket from me for $30 plus shipping after a pretty heated bidding war. I had posted pictures of the jacket from multiple angles and taken close up shots of the size tags. I clearly stated that I do not accept returns. It took nearly a month, but before long I got an email from Jacket Girl that went like this:
Her: This jacket doesn't fit me at all. It's too narrow in the hips. I want my money back AND I want to keep the jacket.
Me: I clearly stated the size in the listing. I'm sorry it doesn't fit, but I don't do returns, as I said earlier. And why on earth would you want to keep a jacket that doesn't fit?!
Her: The jacket is too long.
Me: There were multiple pictures of the jacket with the listing so you could see that. If you want, you can ship the jacket back to me and I will refund you the cost of the jacket, but not the shipping.
Her: (sound of crickets chirping)
Final outcome: I told ebay I was sticking with my no returns policy. They said the seller might give me a bad rating. I said oh well.
Moral of the story: It sucks when you buy something non refundable and it doesn't fit. Just do what I do-turn around and sell it on eBay.
So there you have it. Using eBay to sell stuff you have laying around in your closet is a great way to make a little extra money. And there are mostly nice people out there. But be prepared to deal with Internet psychos. Who now have your home address. Awesome.
