How much do I save at 50% off $89.99?

Is 50% off plus another 50% off the same as 100% 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 $48.59 on a $45.00 subtotal, not 8% of $89.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
