Well, Sony electronics are not returnable. So if our store doesn't sell them, they eventually get marked down. First to 50%, then 75%, and finally $1. Apparently, my manager didn't think it was a good idea to mark down such a high priced item, so it just sat around for a while.
I never even knew it was supposed to be marked down. But once everything was $1 and I noticed some headphones and things, I decided to scan one at the register. Shockingly, it did indeed ring up at a dollar. So, just to be sure, I cleared it with a manager (who said it was fine as long as she could have the other one), and that was that.
So . . . keep an eye on markdown sales in unlikely places (I work for a book, music, movie retailer).
