I came here to say this. It's really a great service, but it is not available for the iPhone (Flash) so I always have to use it on my laptop (trade one problem for another) which is kind of a pain. But I do use it all the time and highly recommended especially to avoid having to cancel subscriptions.

People are surprised when I point it at them because it is almost as if BoA does not want you to use it. Check the right side bar towards the bottom.

Ya I've been thinking about reverse-engineering it to write something like the privacy extension for a while... nice to see someone else put in the work!

It was originally offered by MBNA, and it hasn't had any development since BofA bought them. It appears almost purposefully impossible to find.
