OPW -- Apr 2 -- Lavalife has been unique amongst top tier dating system for the longest time, offering members a credit based billing system. That's now changed, as of mid-March. Lavalife membership is now $29.99 a month. The credits based billing system was especially appealing to twenty somethings and, I think, to those more interested in casual relationships. The youngsters are more likely to be on social networks these days. Older people are more likely to pay for online dating. Lavalife is shifting it's focus, ever so slightly, by changing it's billing system.
