I swear by the deals at CVS. If you have the time for reading the adds and you don't mind buying in advance of your actually needs, you can save lots of money. Today I made my weekly run and saved so much. My total came to $24.24 after saving $52.43 with coupons and sales. In addition to this I earned $9 in Extra Care Bucks to use next week. Basically this was a net $15 purchase, less than the cost of the diapers alone which were originally $10.49 each (see below).
I bought 2 boxes of facial tissue, 2 packs of batteries, 2 bags of diapers, 1 dishwasher detergent, 3 cold medicines, air sanitizer spray, breakfast bars, etc. These are all things I'll use, maybe not all this week, but I'll use them. We have a section in the garage where we shelve these things.
Final note: I know what you're thinking, why do my kids need diapers. They're for night time only okay. I like to think that they're too busy dreaming up ways to save the world and solve complicated math formulas that they don't wake up to go to the bathroom - sometimes :)
