UPDATE: Looks like promotion is over for now. They say a new one is coming soon. Will let you know when it is up.
Honey Bunches of Oats offers a great $2.00 off any one box of Honey Bunches of Oats on their site.
The coupon is on the bottom right hand side of the site. If you have printed the coupon before yo may not be able to print it again but it does seem to reset every so often so worth checking out.
