70% of $4.99 is $3.49, so the price drops from $4.99 to $1.50. Below are the same figure with sales tax added, what happens if a second discount stacks on top, and the full tier table for this price so you can compare without retyping it.
The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 70 ÷ 100 | 0.70 |
| Discount amount | $4.99 × 0.70 | $3.49 |
| Final price | $4.99 − $3.49 | $1.50 |
| Price paid, share of original | $1.50 ÷ $4.99 × 100 | 30% |
At $0.05 per percentage point, the 5-point move up to 75% changes the saving by $0.25 on a single unit. Two units bought at 70% save $6.98 between them, which is $3.24 more than one unit at 75% ($3.74) — quantity and discount rate are separate levers and they do not trade evenly.
With sales tax on top
Tax is charged on the discounted amount, so the rate applies to $1.50 rather than $4.99.

|---|---|---|
| 5% | $1.57 | $0.07 |
| 6% | $1.59 | $0.09 |

"Take an extra 20% off sale prices" is a second cut on the already-reduced price, not on the original. That is why the totals below do not add up to 80% or 90%.

|---|---|---|---|
| Extra 10% off | $1.50 | $1.35 | 73% total |

Frequently asked
What is 70% off $4.99?
$1.50. The discount is 70% of $4.99, which is $3.49, and that comes straight off the price: $4.99 − $3.49 = $1.50.
How much do I save at 70% off $4.99?
$3.49 on a $4.99 item, which is the 70% that comes off before the till total of $1.50. 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 $4.99 the first cut leaves $1.50, and a second 70% takes it to $0.45.
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 $1.62 on a $1.50 subtotal, not 8% of $4.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
