Shopping tips
US shoppers: prices on shelves are pre-tax. Use this to calculate real out-the-door cost before deciding to buy.
For receipts where you want to verify the tax line, use "Extract tax" mode — paste the total, see the implied tax.
For tip-on-tax decisions (US restaurants), some calculate tip on pre-tax, some on post-tax. Use this to figure out either.
