How much do I save at 40% off $99.99?

Is 40% off plus another 40% off the same as 80% off?

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 $64.79 on a $59.99 subtotal, not 8% of $99.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
