International shipping on
Gilt seems to be cheap. There are several problems however:
1. Some items can't be shipped outside the US.
2. Sometimes shipping is more than $19.95. I don't really know how they calculate their shipping rate. May be they quote Fifty One showing the weight and size of the items.
Another problem is that Fifty One uses DHL Express only. Although they usually deliver much faster than USPS, it is not a state postal service. This causes problems like 200 EUR limit for avoiding customs fees and duties when shipping to Russia. The same applies to many other countries where the usage of state postal services is benevolent.
