Unit pricing is not always best because they have different sizes, select a size for instance so 2 sheets equal 1 regularsheet yet the price is per sheet so it looks like your getting more.

You need to look at each product, size of the sheets, number of plies, select a size or regular then use a calculator and divide price by number of sheets.

Even looking at unit price on different brands can be confusing.

At walmart some liquid items are per ounce, some per quart. Some per pound as stupid as that is.

Ice cream can be per pint, per quart or per ounce so you really have to us the calculator to make it all per ounce so you can compare fair and square.
