How much do I save at 10% off $149.99?

Is 10% off plus another 10% off the same as 20% off?
No. Stacked percentages multiply, so 10% then 10% is 19% off in total, not 20%. On $149.99 the first cut leaves $134.99, and a second 10% takes it to $121.49.
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 $145.79 on a $134.99 subtotal, not 8% of $149.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
