Also, my son and daughter work for a shop that does these shirts/hoodies/hats/etc. My son has done design work and has his own little side business selling logo products. Might be able to get a deal on them there if that helps to increase the donation potential or drop the purchase pricing while holding the donations the same maybe picking up more volume. Food for thought.
I think long term, having a constant "store" for the shirts and other paraphernalia along with everyone doing consistent "membership" donations might be better than SuperDan getting frustrated at lack of support and the burst to make it up. I have been super busy with building a new house/shop and totally missed all the potential shut down. Read up last night and was really impressed by all the rallying support. I have personally just donated the recommended amount every year. from shortly after I got back into my 240Z project and found this site. I don't financially support many of these forums but this site is really a great place to be with great people and information so I felt it was important to support.
Let me know if I can help out.
