Shipping is flat rate 4 eur Worldwide.
It is done via Bulgarian Post and takes usually 4-5 business days to EU and 7-8 to the rest of the world. Sometimes more for unknown reasons.
There is a tracking ID, though it is not updated quite often, but maybe it would help if a package is lost. (so it will not tell you like DHL - that package will arrive at X o'clock on Z day :) )
