Is there any site you can find out about the 'bonus features' of credit cards?
Billshrink offers some pretty neat analysis tools to help you pick a credit card. They focus more on rewards than the features you mention but it might be worth a look. If you use Mint, they offer a similar service, too. If you're not already using Mint, though, I'd look at Billshrink as Mint requires some extensive setup. MOD EDIT  Looks like billshrink.com is shut down.  From their site: Dear BillShrink customer, As you may have heard, BillShrink.com was shut down on July 31, 2013.   While we’re sad to say goodbye, we hope we’ve been able to help you be   better informed and save some money along the way! The good news is   that much of the innovative award-winning BillShrink technology will   still be available via our StatementRewards platform (made available   to customers by our partnering financial institutions). Moreover, we   expect to re-launch a new money-saving service in the future. To see   more of what we’re up to, visit Truaxis.com. We have deleted your personal information as of July 31. We will   retain your email address only to announce a preview of the new tool.   If you do not want us to retain your email address, you can opt out in   the form below. This opt out feature will be available until September   31, 2013. If you have already opted out previously, you do not need to   opt out again. If you have any further questions, contact us at   info@billshrink.com. Thanks, The BillShrink/Truaxis Team
