Do macbooks ever go on sale or when do they have the deals?

I worked there for a few years and black friday they do some kind of small promo, and always for back to school they do the free ipod thing with a computer. They offer smalls discounts to different business and such. But the % at most is 10... employees get good discounts... also a trusted person on ebay that you notice sells a lot of apple products, prob works for apple. lol...
