The prices in our shop (http://tri.gg/shop) are in GBP, and it looks like all the prices have been listed at the same value, but in USD the Amazon.com shop (so, a product costing £20 is listed as $20 instead). Obviously, this is a problem (luckily only a few customers bought at the wrong price...)

What's the best way to deal with this? Should I add a % inflation on it? (And if so, would I enter 170%, or 70%?), or is there an automatic currency converter hidden away somewhere? If so - where, and how do I use it? 

I have seen the "Price Units" in listing setup, but it's not clear to me whether this needs to be set to the target currency or the source currency, and the help text doesn't offer much help on that front.
