MixMyGranola.com lets you customize granola just to your liking.
The site updates the price of your granola and gives you a status nutrition report as you go along, so you can make it as healthy as you like. (Sure, dark chocolate has antioxidants, but I'm not sure how you can justify the gummy bears. Oh right. They're organic!)
The base granolas start at $4.49 and add-ins range from 49 cents to $2.49 each. Your mix gets you a pound of granola. Mix a batch for everyone in your family because if you spend more than $40 you get free shipping.
For the indecisive or unsure, Mix My Granola also offers pre-mixes ($6.99 to $11.99) specially blended by flavor ("Let's go nuts!" for nut-lovers), activity (Runner's Mix) or goal (like weight loss or lowering your cholesterol).
