How to compare prices correctly
Why the lowest displayed item price is not always the cheapest overall offer.
Compare the total cost
Consider the product price together with known delivery charges. Minimum order values and delivery conditions can change the final cost.
Currency and market
Offers from different countries can use different currencies, taxes and shipping terms. The selected market therefore matters for useful sorting.
Make sure it is the same product
A meaningful comparison requires the same trade item. Variants, pack sizes and accessories can have separate GTINs.
Check freshness
Merchant feeds and product data change continuously. The merchant destination page is the final reference for current price and availability.
