We have seen great prices on cereal at multiple stores recently! I personally believe the best price right now is the Kroger Mega Sale on most of them!
The Cinnamon Toast Crunch Cereal is priced $1.88 currently when you 6 participating items on the Kroger Mega Sale - use the new $.50 off coupon and pay $1.38 per box!
Golden Grahams Cereals are priced $1.88 currently on the Kroger Mega Sale when you buy 6 participating items. Use the new $.75 off printable coupon and pay $1.13 per box! Great price
Chex cereals are part of the Mega Sale also. Prices starting at $3.19 per box. However you may find a better deal when these are on sale at CVS or Walgreens for around $2 per box.
This has been a great time to stock up on cereal from store to store. So definitely check around when you are out and see what is the best deal for your family!
