Prorated Memberships

All STS memberships are renewed in October.  New members are charged a prorated amount in October.  The amount is defined by the amount of time you have been a member. 

For example, if you join STS just 3 months prior to renewal (August 1), then your renewal rate in October will be equal to 3 months of membership.  So if you paid $24 in August, your renewal in October would be $6.  This is calculated by dividing $24 by 12 months, for a monthly cost of $2, then multiplying that amount by the number of months prior to renewal, which is 3 months:

$2 x 3 months = $6 renewal
Effectively, you are retroactively paying a monthly fee 
for your membership prior to annual renewal.
