Here’s a deal on Kashi Cereal over on Amazon.com. You can get 4 boxes of Kashi GO Lean Crisp Cereal for around $10.61 including shipping when you use subscribe and save.
This works out to around $2.65 per box including tax and shipping.
To compare, Target had Kashi Cereal on Price cut for $2.99 last week and there is a $1 Coupon on Coupons.com. So in my area I would pay around $2.26 including tax after the sale and coupons, so it’s a little bit more expensive on Amazon than combining a sale and a coupon but you don’t have to leave your house or clip the coupons :)
