I must admit that I grinned when I read the article about living without paper towels. That's how I grew up – paper towels didn't exist there either! And the idea of eliminating one simple item from the budget got me thinking about other simple ways to save.
So, here's another idea where little savings can add up over time:
Use a soap pump, and dilute dish soap and hand soap. We've been doing this for at least three years. I've replaced the dish soap pump once and buy the hand soap pumps when Bath & Body Works has a promotion. If you use soaps acquired through bargain shopping at CVS and Walgreens, you can really save!
I fill the pumps about 1/8 of the way with undiluted soap (Dawn, Palmolive, SoftSoap, store brand, or whatever's free or almost free!) and then fill the rest of the way with water. So, for the dish soap, I fill only up to the "250 pumps" line with soap. For the hand soap, I fill only up to just under the product description lines (second from the bottom). Voila – savings!
