On 2 different days I listed something and both items sold within 10 *seconds* of submitting and...

...both items were sold to the same buyer.

I do not see how this is even possible.  Even if this buyer happened to be searching for what I was selling at the *exact* moment I submitted my listing, I don't see how he could open the listing, click Buy It Now and get his payment over in that impossibly narrow window of time.

In reviewing his profile, he appears to be legit (only positive feedback, but all FB is from being a buyer) with 17k total, and 5400 in the past 12 months.  The payment cleared okay, but it just seems crazy that this could happen twice.  Is there some crazy setting you can do to automatically purchase something you're following if it falls within a certain price?

There are programs that will do that for you. 

P.S. I wish I had your problem!

Ayup. His strategy is probably to buy everything in that category, whatever it was, that's below a certain price. He might have other restrictions on his buying order, such as to buy only from sellers with higher than "n" number of feedback ratings, or only 99.5% or higher, that sort of thing. You can get third-party apps for doing this. He might buy everything for resale in a B&M store, perhaps in another country.

Hopefully he isn't a serial returner or canceller as well. There were a few semi-automated used-book buying accounts active here a few years back that were notorious for doing that, sometimes filing for a return before the item had even arrived, or claiming a SNAD with ludicrous excuses, some entirely fictional. Hopefully your buyer won't turn out to be one of those. (What was it you sold, anyway?)

Guess I am just too old school nowadays... even though I've been selling for 14 years now.

Thanks for your help!  I do feel better about this now.
