Ask HN: Which SSL?

We're going to be releasing a mobile app soon, which will connect to our API hosted on AWS using Beanstalk.

We'll need SSL for the API, main website and admin panel.

I'm not sure which SSL certificate we should get, and if we should get multiple certificates or a wildcard certificate.

I saw a SSL service posted on HN recently - https://getssl.me/en - Would the Comodo WildCard SSL do?

Thanks
