FAQ

Is 20% off plus an extra 10% off the same as 30% off?

No — it’s 28% off. The second discount applies to the already-reduced price: 100 × 0.8 × 0.9 = 72.

Is sales tax charged before or after a discount?

Usually after: you pay tax on the price you actually pay. Manufacturer coupons can be an exception in some US states.
