Buy or Wait Calculator

Would you wait 14 days to save $20? Buy or Wait Calculator is not a price predictor. It does not guess whether a sale is coming or tell you what a product will cost next week. Instead, you enter today's price, the price you would be happy to pay, and how long you are willing to wait. The app makes the tradeoff between money and time visible. Use it for planned purchases where timing matters as much as price. Price trackers tell you what changed. Buy or Wait helps you decide whether the savings are worth the waiting for you.
