Thats a pretty good deal. I wish I could go home.
I think it would a good idea to buy tickets from Nepali travel agencies as long as the price they give is similar to the one you find online. I am not a travel agent or anything but I think its good to support a Nepali fellow than a multinational company like expedia. If more people buy from these agencies, they might be able to bring some deals for us too. I used to buy online but these days I started buying with these people as long as they give me a similar quote. Even in this case, buying from Qatar Airways website may not a big deal for QA if 10 extra Nepali buy the ticket but it could be a huge boost to any Nepali agency.

p.s~ I am not making a suggestion to a buy from a specific agent.
