Why does the same item have three different prices?
Each site has its own catalogue, sellers and promotions. The price shown also includes the VAT of that country, which is not the same everywhere. Once converted into francs, the gaps between the three sites become visible.
Which site is usually the cheapest?
amazon.de has the widest catalogue and often wins on electronics and appliances. On toys or beauty, amazon.fr and amazon.it regularly take the lead. Chipo compares the three sites item by item.
Is the language of the product page a problem?
Rarely in practice. Your browser translator makes the page readable in one click. You then order as usual.
Do you need a separate account for each site?
No, one Amazon account works on all three sites, with the same address book. The basket, though, is not shared between sites.
Amazon's rates and rules change, the final price always shows in the basket before you pay. Today's price gaps are on the homepage.
