Increase Your Support

Thanks very much for considering increasing your support of AAC. We really appreciate it.

Two options:

  • Annual Membership at US$36—same benefits as your existing membership.
  • AAC Supporter Annual Membership at US$120—for those who wish to support AAC at a higher level.

Any amount unused on your current membership will be automatically deducted from the first year of your upgraded membership.

How To Upgrade

First, please login if you are not already:

Three easy steps:

  1. Click on Change Plan, next to your current subscription in the box below.
  2. A box will pop up showing what your payment will be with each option, prorated for the first year.
  3. Click on your choice.

  • If you don’t see “Change Plan” it means you have a 1- or 3-Year non-recurring membership so, unfortunately, you will need to wait until your current membership expires before selecting whatever membership you prefer, but thanks for considering increasing your support now.
  • If your current membership is Annual, rather than Legacy Annual, you will only be offered Supporter Membership, since you are already paying $36/year. Thank you.
