if you are too tired to do all the math

... let me do it for you. :)
catch these cool deals:
(note: I do not know what Walmart might have on sale this week because they only had school supplies in their weekly ad this week.)

The best deal on backpacks this week are at Walgreens.
Buy 1 get 1 FREE starting at $9.99 (other stores start at $12)
Walmart had backpacks for $9.99, but not BOGO

12pk sodas this week are cheapest at CVS.
4/$11 - but that's only for Dr.Pepper
Walgreens has Dr.Pepper AND Coke 3/$11
but if you love Pepsi products, go to Target because they are 4/$11!

2 liter sodas this week are cheapest at CVS.
5/$5 - but again, only Dr.Pepper
Walgreens is 4/$5 on Dr.Pepper AND Coke

Cereal this week is cheapest at Target.
get 17oz Frosted Flakes or 14oz Cheerios 4/$7 (that's $1.75 a box)

Ice Cream this week is cheapest at Walgreens.
2/$4 on Walgreens brand ice cream.

Huggies are this week's big name diaper sale. I guess Pampers and Huggies hate competition.
They are cheapest at CVS at $8.99 for a jumbo pack.
HOWEVER, if you're looking for bulk, Target has both Huggies and Pampers special purchase diapers for $28 a box. (up to 192 count Huggies diapers and up to 192 count Pampers diapers)

Colgate toothpaste was another popular sale this week.
Target wins this one with their 3 packs of Colgate toothpaste for $5 (1.66 a tube)
They are around $1.99 at CVS and Walgreens.
Target also has Crest 3 packs also $5.

Because of so many places running out of supply of back to school items, it's too hard for me to call the best place to go for school supplies right now. Definitely check out Office Depot for the penny sale. Supplies are limited and it's always a good idea to go as quickly as you can when that happens because you can't get rainchecks when it states limited supply. Good luck!!
