Method & sources
Saving = price × discount ÷ 100, and sale price = price − saving. Amounts are rounded to the cent only for display. Stacked discounts multiply rather than add — 20% off and then another 20% off is 36% off in total, not 40% — and sales tax, where it applies, is charged on the discounted price.
