Where is 'is'?

I arranged for ten copies of "IS" to be sent to me here in Vietnam by the publisher, Adlibbed Ltd. Three weeks' later, still no sign of them. Frustrating isn't the word. The book is selling: I have orders to fill in the UK and France, as well as copies sold here in Vietnam - and yet I have yet to hold a physical copy in my hands.

I have heard (unsubstantiated) reports of books ordered online not making it through Vietnamese customs and ending up
(a) on sale in Fahasa (the State-owned foreign language bookshop in Vietnam) and
(b) photocopied and for sale in the backpacker district.

It would be incredibly annoying to discover that I couldn't get my book through customs!!!
