That is pretty much not true brother
Lettuce and other produce are 50% to 70% cheaper at a dollar store then typical named brand stores
For the same amount of lettuce on an Apple’s to Apple’s basis? I don’t really know but it would be interesting to see somebody do a comparison.
Some stuff it works out like that. Other stuff not so much. A lot of dollar store stuff is just much smaller. .8 ounce deodorant sticks instead of 3 oz. And when you work the math dollar store is more expensive per volume. As always one has to watch what you’re getting and pay attention. Stretching dollars takes work, you can’t just go to the store that says they’re cheap and assume.
