Contena themselves are less than up-front with their pricing. They say, in their FAQ, that their pricing "starts around $40 per month when paid annually." That's an up-front payment of almost $500 for a year of access. They also have a premium membership that runs $800 per year. Of course, both versions can be broken down into 5 monthly payments instead of paying all at once, with the commitment. The monthly payments are $100 or $179 per month, respectively.
