If you are a Member already, please login first, with your member email address, so your donation will be linked to your membership information. Unfortunately, WildApricot currently only provides for online payment of donations (no "Invoice me" option). But you can send a check (and combine it with your membership renewal if you like) payable to "APCG" to:
APCG/Dept. of Geography, CSU Sacramento MS 6003, 6000 J Street, Sacramento CA 95819.
Include with it a simple note saying which fund(s) your donation is for; I'll create the invoice and mark it paid.
If you need help contact me at <email@example.com>. --Bob Richardson (Treasurer)
