Officially when importing item from outside of EU you should be billed with VAT + customs. It is usually done that way that on border packages are inspected by officers in magazines of importer.
If you order item directly from on-line shop, they are obliged to package items in such way that officers will knew what is inside and you will be billed almost automatically.
You can get around it: ask family, acquitances to buy it and send you in normally wrapped package (or just bring it with them if they are visiting your area).
Such packages are inspected at random and you have chance that you will not pay additionally. Note however that you should earmark those money because chance for inspection is always.
With smaller difference in price with N900 than with N8x0 + lost guarantee + not so weak USD I don't think game is worth it this time.
