Frequently asked
What is 50% off $19.99?
$10.00. The discount is 50% of $19.99, which is $10.00, and that comes straight off the price: $19.99 − $10.00 = $10.00.
How much do I save at 50% off $19.99?
$10.00 on a $19.99 item, which is the 50% that comes off before the till total of $10.00. The share you still pay is 50%, and sales tax is charged on that smaller figure rather than on the original.
Is 50% off plus another 50% off the same as 100% off?
No. Stacked percentages multiply, so 50% then 50% is 75% off in total, not 100%. On $19.99 the first cut leaves $10.00, and a second 50% takes it to $5.00.
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 $10.79 on a $10.00 subtotal, not 8% of $19.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
