Our calculator handles multiple discounts with precision. It applies discounts in the order you would typically encounter them in retail scenarios: percentage discounts first, followed by fixed amount discounts. This mirrors how most stores process stacked promotions. For example, if you have a 20% store-wide sale plus a $10 coupon, the calculator first applies the 20% discount to the original price, then subtracts the $10 from that reduced amount.

While the calculator displays results in dollar format ($), you can use it with any currency by simply entering amounts in your local currency. The calculations work the same regardless of currency type. For example, if you're shopping in euros, enter prices in euros and the results will be accurate for euro amounts. We're working on adding currency symbols and localization in a future update.

Our calculator shows you the final price, but determining whether it's a "good deal" depends on several factors: the item's historical price, competitor pricing, and your personal budget. We recommend: 1) Checking price history tools (like camelcamelcamel for Amazon), 2) Comparing across multiple retailers using our calculator, and 3) Considering the item's value to you personally. Sometimes paying slightly more from a retailer with better return policies or customer service is worth it.

Yes, though you'll need to calculate the per-unit price first. For "Buy 2, Get 1 Free" deals, enter the price of two items as your original price, then apply a 33.33% discount (which represents getting three items for the price of two). For tiered pricing (e.g., "10% off 5+ items"), calculate the per-item price after the quantity discount, then use that as your original price if applying additional discounts.

Discrepancies can occur due to: 1) Stores applying discounts in different orders (some apply coupons before percentage discounts), 2) Hidden restrictions (like certain brands being excluded), 3) Rounding differences in their systems, or 4) Additional fees (like shipping) that aren't included in our base calculation. Always double-check the store's final price, but our calculator gives you a very close estimate to spot-check their math.

Currently, we offer a mobile-optimized web version that works on all smartphones and tablets. You can save our website to your home screen for app-like access (on iPhone: tap the share button and "Add to Home Screen"; on Android: tap the menu button and "Add to Home screen"). We're developing native iOS and Android apps with additional features like price history tracking - sign up for our newsletter to be notified when they launch.

For tiered discounts like "$10 off $50" or "15% off orders over $100": 1) First calculate your cart's subtotal, 2) Determine which discount tier this qualifies for, 3) Enter that discount in our calculator. If you're close to a higher discount tier, our calculator can help you decide whether adding another item to reach that tier saves you money overall. For example, spending $15 more to get from $90 to $105 might qualify for "20% off $100+" which could save you $21 (net $6 savings).

The current version doesn't save calculations automatically, but you can: 1) Take a screenshot of your results, 2) Bookmark the page with your values entered (they remain in the form until you refresh), or 3) Copy the calculation details manually. Our upcoming premium version will include saveable calculations, comparison tools, and price alerts - join our waitlist to get early access.

Manufacturer's Suggested Retail Price (MSRP) can be misleading, as items often sell below MSRP normally. For "% off MSRP" claims: 1) Enter the MSRP as your original price, 2) Apply the claimed discount percentage, 3) Compare the result to the item's typical selling price (not MSRP) at other retailers. Many "50% off MSRP" deals are actually selling at or above normal market price - our calculator helps reveal this.

Absolutely. Our calculator runs entirely in your browser - we don't send your price data to our servers or store any financial information. The calculations happen on your device, ensuring complete privacy. We don't require accounts or collect personal information to use the basic calculator. For future premium features that might require account creation, we'll use bank-level encryption and strict privacy policies.
