Shopping offers should be easier to compare.
Ship or Spend is a collection of free decision calculators for the moment when a discount, bundle, membership, subscription, or warranty makes a simple purchase feel complicated.
Why the site exists
Retail offers are usually advertised using the biggest-looking number: “free” shipping, 20% off, a yearly saving, or an extra item included. The meaningful number is the final cost. Our tools normalize competing offers and explain the difference in plain language.
Our principles
- Useful before clever. The answer and calculator come first.
- Private by default. Calculations happen on your device without an account.
- Current without constant updates. You enter the prices you see, so results do not depend on stale retailer data.
- Honest about limits. We show formulas and assumptions instead of pretending every purchasing decision is purely mathematical.
Independent tools
Ship or Spend is not a retailer and the calculator results are not personalized financial advice. Advertisement spaces are visually separated from calculator controls and do not determine the result.
