How to find bargains at Amazon

I've got an Amazon gift certificate burning holes in my pocket, and I want to get the most bang for my buck: enter the Amazon bargain basement, aka Today's Deals and the Friday Sale.

First, there's Today's Deals. This is where you're going to find the "latest sales, rebates, and limited-time offers" from Amazon, and you can score some pretty deep discounts if you're a savvy shopper.

Next, there's the Friday Sale. This is open every Friday, and ONLY on Fridays. You can find the same good discounts here as you would in Today's Deals, although some Fridays you can really get lucky and make off like an Amazon bandit - I've seen discounts there as low as 75% off sticker price.
