Cheap .RS domains - A tip from a Serbian fellow
I'm from Serbia and I can recommend these two ISPs which sell .rs domains:
https://www.oblaci.rs/preview/domentransfer (mts.rs is the company behind it, it's our own government entity) costs 1920RSD = \~17USD per year
https://myhosting.sbb.rs/domains/ (sbb.rs is the company behind it, it's across the whole Balkan territory) costs 1900RSD = \~17USD per year
