I've always used moneytonepal and they've been great so far. They've also changed their service rates so you might want to compare between muncha and moneytonepal. With the new change, it costs you less than $10 for over $2000 and $15.99 for $1000-$2000. Once the fund has been cleared from your bank/CC, the money is immediately available for pick up or delivery. I think Western Union is expensive and not a Nepali company, so I don't use it. Support nepalese businesses. Goodluck, Pal !
