Even if it wasn't a sale, I guess I bought my laptop for a pretty good price. It was about 600-700 in dollars, and it's a good laptop, can run most games on medium to high graphics. Even though the newest games start to be a bit heavier, but it can still run them pretty good.
Other than that, me and my friends bought out a whole shelf of beer 4-packs which were on sale and cost about a dollar or so each.
I can't remember getting any particularly good deals I got but I do remember a story from a Macy's employee. According to him, a lady came in and got $50 dollar shoes for $1.50 with a bunch of coupons and discounts.
Once, the ART SUPPLY STORE where I worked got a shipment of Dance Dance Revolution: Highschool Musical to sell for christmas. Because it's an art store and people don't go there to buy videogames, it's not surprising that they didn't sell out after the christmas rush. Or by like, Easter. Eventually one of my friend's birthdays came around, and this person wanted a DDR mat so she could buy the disks for the game. The DDR:HS copies (complete with mat and game) left at the store were on their last legs in the clearance aisle at 2$, so I bought her one as a joke. xD The game is usually like 50$.
