Does sales tax apply before or after the discount?
After, in every US state that taxes the sale. Tax is charged on what you actually pay, so at 8% you owe $25.92 on a $24.00 subtotal, not 8% of $79.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
