The best thing you can do for Black Friday is nothing: those discounts aren't worth the indignity of getting clobbered by an octogenarian's purse while she hunts for a Frozen doll. But if you swing by this promotional page for Amazon's Appstore, you can pick up no less than 40 free apps and games, worth a combined $130 at full price. Amazon does these promotions on a regular basis. There's no reason not to get them all, but if you'd rather not clutter up your Amazon account, here are some notable picks:

Some of the apps are duplicates, like the Kindle Fire-only Angry Birds (the one above is fine for non-Fire devices). We're assuming that the promotion is only good for the United States, and I'll bet the prices will go back up after tomorrow.
