Well, obviously I cant (nor want to) share illegal sources and most of the books are copyrighted... In the remote case that it really was the only option for you I recommend picking a particular title and searching for it rather than trying some general search. I am sure you will be able to find something after some effort.
Otherwise, on the off chance you have not noticed, there are some books to check out in the https://online-go.com/docs/other-go-resources page I mentioned earlier (under books, duh ) Shape up is a great free book for example, but it is rather concerned with shape then tesuji, and perhaps for little more advanced players...
You can try browsing through this forum for some tips on books: http://lifein19x19.com/viewforum.php?f=17&sid=5b20d01d017c6b5384f1ef8e6e24f772
If you are (for some reason) using apple devices I have heared there is a great app with go books for free or for reasonable prices.
Other than that I really don't know what else to do. It is the 21st century If the problem with buying books in your country is related only with shipping you can of course buy most of the famous books in electronic formats (unless you are unable to use PayPal or credit cards allthogether...)
