Right now it's 7.05 according to XE. However, it's mid-market rates, right between the buy and sell values. Buy/sell rates are typically 10-20c around this (higher and lower, so 6.85 - 7.25). On Monday it was 7.21 (I drew up some quotes for a client, and that's what I wrote down from XE). The rate can change extremely fast. If you write an article it may take weeks for to be published, so exchange rates are rarely accurately stated. The article writer may also want to make sure he doesn't understate the prices.
In addition, importers often have forward cover on exchange rates, where they lock in the rate at a specific value, sometimes higher, sometimes lower. The price they import at may have nothing to do with today's spot price.
