Common Questions Answered

Quick help
Q1 How do I calculate a discount price?
Multiply the original price by the discount percentage (as a decimal), then subtract that savings amount from the original price to find the discounted cost.
Q2 What are stackable discounts?
Stackable discounts occur when a secondary coupon percentage or a flat cash deduction is applied to the already reduced price of an item.
Q3 Is sales tax applied before or after discounts?
In most jurisdictions, sales tax is calculated based on the final discounted sale price, rather than the initial retail price.
Q4 How do I find the original price if I only know the sale price and discount?
Divide the sale price by (1 minus the discount rate expressed as a decimal). For example, if an item costs $40 after a 20% discount, the original price was $40 / (1 - 0.20) = $50.
Q5 Are my shopping items or pricing inputs tracked?
Absolutely not. All markdown algebra is computed client-side in the browser. No input variables are ever logged or sent to remote servers.
