$600 = 1 t-shirt?
really? >:(
How about a pin or something unique that we can proudly display? Not a t-shirt, like the ones you give away free to volunteers at a rally…
Would it make a difference if Charlie P wore it for a day? 
I do agree though a t-shirt as a thank you is a little weak. Maybe a discount on BJCP testing for lifetime members or a voucher for a couple free entries to the NHC competition.
Or nothing at all except the feeling of supporting a great organization.
How about… membership in the AHA for the rest of your life?
Alll the rest is lagniappe.
good word! had to look that one up!
Never been to New Orleans, huh?
and Signed it… Yep!
