Save 15% on Amazon.com

Get 15% off certain groceries and household items when you agree to purchase them regularly through Amazon.com's subscribe and save program.

The way it works is you sign up to buy, say toilet paper, every one, two, three, or six months. You get 15% off the Amazon price and free shipping. They email you when a shipment is coming and you can change the delivery schedule or cancel whenever you want. It saves you the trouble of going to the store and remembering not to run out of tp, though I suppose you have to monitor their prices once you sign up.

Eligible items include dozens of products in six categories, including household supplies, food & snacks, personal care & beauty, health & wellness, baby & child care, and nutrition & energy bars.

For a 15-pack of Luna bars they normally charge $16.56. Through the subscriber program you save $6.02 on shipping. The 15% subscription discount comes to $2.48, bringing the total to $14.08.

That's $.94 per bar, much lower than the $1.50 you typically pay in grocery stores. Not sure that beats Costco. Any Costco fans know how much they cost there?
