The current price of the item indicated in the currency of the site on which the item is indicated. That is, currentPrice is returned in the source currency.
For competitive bid lists, the current price is the current minimum bid price if there are no bids in the listing or the current high bid, if bids are listed. The price of Buy It Now does not affect currentPrice.
For basic fixed prices (fixed price), store inventory (StoreInventory), ad format (AdFormat), and classified ads (classified), the current price is the current fixed price.
