And how about price comparison, is it mandatory for US supermarkets to display the price per unit based on a standard unit of measurement (such as per pound or per ounce or whatever metrics are used)?
Depends, generally no. Some supermarkets do as a company policy though and I choose to shop at those that do show per-unit pricing (and are also locally/employee owned)
So, if these prices can be so easily updated, surely the retailers can now include tax in the listed price. It’s very simple automated math of course…
Wait, you’re telling me that the price on the shelf doesn’t include tax where you live?
It’s standard in the US for the listed price to not include any taxes.
