And that's how it's typically done when the Euro is worth more than the US Dollar: either multiply by the FX rate to get a price in Dollars or divide by the inverse of the FX rate to get the same price. In you example, either divide by 0.9 or multiply by the inverse, i.e., multiply by 1.111 (as 1/0.9 = 1.111).

However, after reducing the listed Euro price by the 19% VAT charges, adding only shared shipping costs, and reducing it by my volume discount, the final cost of the model in Euros is so much LOWER than the listed full price, that even multiplying by it by the FX rate of 1.12 - 1.14 results in a number lower than the LISTED number. So, for me and interested collectors, I recommend simply taking the full Euro price and multiplying it by 0.95. Very simple. But it is a rough price. For example, the Schuco RSR Porsches are listed for Euro 169.95. Take that number 169.95 and multiply by 0.95 and you get the number 161.42. That's very close to my price of US$160. Got it?

If you'd like, I'd be happy to email you - or even post - the full formula as I've got nothing to hide.
