Frequently asked
What is 70% off $99.99?
$30.00. The discount is 70% of $99.99, which is $69.99, and that comes straight off the price: $99.99 − $69.99 = $30.00.
How much do I save at 70% off $99.99?
$69.99 on a $99.99 item, which is the 70% that comes off before the till total of $30.00. The share you still pay is 30%, and sales tax is charged on that smaller figure rather than on the original.
Is 70% off plus another 70% off the same as 140% off?
No. Stacked percentages multiply, so 70% then 70% is 91% off in total, not 140%. On $99.99 the first cut leaves $30.00, and a second 70% takes it to $9.00.
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 $32.40 on a $30.00 subtotal, not 8% of $99.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
