Our approach
Why the lowest sticker price may not be the lowest total
Compare the purchase price plus required shipping and fees. Sales tax is not included.
Compare what you would actually pay
When shopping is available, our offer comparison will use the exact product and pack, required fees and applicable shipping. A membership, subscription, coupon or larger basket must not silently become the ordinary one-time purchase price. Different seller, delivery or return conditions can also make offers unsuitable for a fair price comparison.
ZIP only when it changes the calculation
If a reviewed shipping policy establishes the cost without your ZIP, we should not ask for it. When location is required, we explain why. If we still cannot establish shipping, we show the uncertainty and do not award a lowest delivered total.
Prices can change
A timestamped observation is not a reservation or a guarantee. Shopping is not available yet. When enabled, current prices, stock and shipping must be checked before sending you to a retailer.
