תרגום - בולגרית-אנגלית - скъпо ли струва при вас интернета?

I changed the word order.

Редно би било преводът да бъде по-скоро така: Скъп ли е интернета (т.е. услугата интернет) във вашата страна?

I'm sorry, but I cannot read Bulgarian, and I need to evaluate the English translation, so if you can help me with that, please write in English.

There should be an article before 'internet'

No - I think it reads better this way. When we say "the internet", we think of the actual virtual space where we search for things, but "internet" is the service provided.

Yes, context is the price Internet service provided. I have got the correct translation, thanks.

You're welcome!
