If you purchased an item that was listed as a Black Friday Apple sale items at one of the Apple Retail Stores, I urge you to check you receipt to see if you got the sale price. I was at the Apple Chicago Michigan Ave. Store on Friday and purchased two sale items (the Nike+ ipod adapter and the Ingroove Neoprene sleeve for the Macbook). While both items were listed as sale items on the in store flyer and on the Apple web site, when I checked out with an Apple associate using a handheld terminal I was charged the FULL PRICE of these items.

Since I discovered this when I got home, I called the Apple Store to request a refund. after a bit of an arguement, i was told i would get a refund in a few days. Today I got a refund on the Nike+ item, but not on the Ingroove sleeve. Looks like I will be calling the apple store again.
I can only imagine the thousands of people who thought that they were getting an item at the sale price and were actually charged full price.
