The beauty of cafepress is that you give them the design and the price you want to charge for an item. Then members of DCC can buy it, knowing that a portion of the price will be returned to DCC. For example, a small magnet is listed at $2.49. If it were listed at $4, DCC would be sent the difference. Since the basic service is free, there would be no DCC outlay of funds, and it could be a source of additional revenue. The downside is that only those people who made a purchase would have something with the DCC logo on it.
If you just want to provide a DCC iron-on logo to every DCC member, you might try something like this:
http://h30094.www3.h...ltimesmb/accessories. I estimate that you could print and ship these iron-on logos for approximately $1.75 each (purchase, printing, envelope & postage). The question is: do you want to send one to every donator? If so, that would be a gift, not a fund raiser (although, if worn, might generate some interest). Or do you want to ask a donator to contribute an additional $2.00 (or $3.00), if he/she would like a iron-on logo? The problem with the latter approach is that you may get only a few takers, and then lose the community and free publicity angle.
Personally, I like the lottery idea, with one of the donated programs as a prize. Or, since many of the members already have these programs, what about having DCC buy the winner (who already has one of the programs that have been donated) any program of his/her choice up to a maximum monetary amount? You'd have to chose that amount carefully, though, in case no one participates in the lottery.
