The price will definitely rise again when these people will renew their package on that website. Right now everyone have their packages but as the time passes everyone will need to renew and they will use verge.
You can
NOT renew with verge, only in initial signup is possible with verge. Tested it yesterday. At this point there is NO way someone can make a recurring membership payment with VERGE, ONLY the first payment can be done with Verge ....
Eventually this will change, but until it happens i would not count on it!
