I found this:
"Coinbase is the largest Bitcoin broker worldwide. It allows users to buy up to $150/week of Bitcoins via a credit card or debit card. Coinbase charges a 3.75% convince fee on all credit card transactions and is open to 33 countries around the world. When buying more than $100 of Bitcoins you will receive an additional $10 Bitcoin bonus.
