Coinbase should be fine for this. They don't seem to charge a fee, and I've been paid faucet earnings via coinbase (not a direct receive to wallet, the email to email thing.) You could also consider having them make a coinbase account. Pretty quick, and you know you'll be able to pay them with minimal fees.
Xapo does too.
I use Xapo for microtransactions since having to pay transaction fees when transferring really low amounts has a dramatic effect.
Electrum has a pay to many function although unlike Xapo, you actually have to pay a fee.
