Tips & Best Practices
- •Tax Applied to Discounted Price: In retail stores, sales tax is almost always computed on the final discounted price, not the original MSRP. For example, if a $100 item is 20% off ($80), an 8% tax is $6.40, not $8.00.
- •Understanding Stacked Discounts: An extra 20% off a 50% clearance item is NOT 70% off. It is 50% off $100 ($50), then 20% off the remaining $50 ($10), giving a final total of $40 (60% effective discount).
- •Sales Tax vs VAT (Value-Added Tax): In the United States, sales tax is typically added at checkout. In the UK, Europe, Australia, and many other countries, VAT is already included in the displayed shelf price.
- •100% Client-Side Privacy: All price calculations, invoice totals, and coupon savings are processed directly in your browser memory with zero tracking.
