Use the coupon code AUGMKDWN at the Amazon.com grocery section and you can save 40% on your order. The offer is good through Sept. 12, and also can be combined with free shipping on orders over $25. There are over 2,000 items on the clearance list, so you can stock up and save on a number of items, from salad dressing to chips to gourmet items.

For instance, a 4-pack of Frosted Flakes, the 17-ounce size, is $17.87 on the site, but with the discount and free shipping (presuming you'd buy something else), you would save $7.15, which makes each box $2.68, which is pretty good compared to super market prices. And you wouldn't even have to leave home!
