Dollar-stores overcharge customers while promising low prices

in 2025 I'm surprised you can't just scan everything on your phone yourself and get the up-to-date price. are there laws stating things must be a posted price? seems easier for everyone to have something you can scan that show you the latest price, or auto updating tags.

Auto-updating tags can be incorrect, too.

Looks like Dollar Tree just rolled out a feature where you can do a price check on items by using their App.
