It adds up really fast. $7/month for an instance then $20/month for ssl (even if you don't want the wildcard) and add another $9/month for backend. $ 36/month

It adds up really fast. $7/month for an instance then $20/month for ssl (even if you don't want the wildcard) and add another $9/month for backend. $ 36/month in 12 month is $432/month That is indeed a cheap service. However, relatively expensive for people not making a profit for their projects. It would be nice if Heroku lowered their prices occasionally as well.
