Marketplaces
JustRanks covers Amazon.com. Prices are in US dollars, and every page is captured as a shopper in the US sees it.
The database holds search results from Amazon.com, the US marketplace. There is no marketplace to choose: every search, market and keyword refers to Amazon.com.
Prices
Prices are shown in US dollars, exactly as the results page showed them. Nothing is converted or estimated.
Location
What Amazon shows depends on where the shopper is: delivery promises, availability and even the order of the results can differ by location. JustRanks captures every page with the same US delivery address, so a change from one capture to the next comes from the market, not from a different location.
Other marketplaces
Other Amazon marketplaces are not covered.
