I think people are misunderstanding the SSL costs for Cusion.
The SSL certificate expense is listed as $99/year from namecheap, ie. $8.25/month, so there seems no need to get a Symantec one.
However they/it/he are paying Heroku $20/month for handling the SSL traffic, not the certificate itself, which probably includes running a load balancing server in front of their apps that automate the SSL termination across nodes. Which seems like a fair cost to me.
I think the description of this cost is the error which causes the confusion.
