I like the UP&UP toilet paper from Target. The rolls had gotten so loosely rolled that each roll seemed to have hardly any paper on it. Target recently switched to bigger rolls of TP that are tightly rolled again. I have to change the roll a lot less often now.
I don't know if it is a stealth price increase or not as I never paid attention to the square feet of TP I was getting previously. The package is smaller with the rolls tightly rolled so Target saves on shipping and warehousing.
TP. Costco. That is all.

The most expensive tool is the one you buy "cheaply" and often...
What, you aren't cutting open your toothpaste tubes and using the little bit that remains in the tube? If you value your time at all this is just a total waste of time. There are a lot easier ways to save maybe $5 in your lifetime.
I consider myself to be somewhat frugal, but I'm not doing stupid things like this. People who do this are cheap, not frugal. I choose what I buy carefully with an eye to buying stuff that will last. Frugal is not necessarily about not spending money.
