It supports local catalogs and currencies for the US, UK, Germany, France, Canada, Japan and many more markets; Czechia uses Amazon.de. It explains compatibility uncertainties and sends users through a SmartCart handoff page to verify final prices, availability, taxes and shipping. Regional Associates tracking is used only when configured; Amazon.com OneLink is offered separately where applicable. SmartCart never completes checkout. Qualifying purchases may earn a commission, which does not determine rankings.",
