We were free members for well over one year before we paid.
Wayne can fill you in re number of years, but then he may feel we didn't pay as we had membership taken out of our affiliate commissions. We wanted to accrue commissions to pay for Lifetime as SLS said you could do that.
It seems that it is better to collect your commissions and then pay separate for membership.
While we waited, Lifetime increased from $99/year to $150/year. We felt it was worth it to pay $150.
