I voted donate/purchase. I'll be donating something, it just depends. I think I'll come out of retirement (lol) to make one reproduction cart, with the
special edition label again, if I can. I mean, I would like to, as that's the best I can do to raise the most money, but I might not have the time. Moreover, I don't make repros anymore, for many reasons, and haven't made any since last year's charity. It's been a while, so I'm out of the swing of it. If I don't end up making one, I will at least try to donate something worthwhile.
As for purchasing... well that depends on what's in the auction!

I'll most likely be purchasing, there has been some neat stuff in the past years.
Question... Will the auction be held on an auction site like it was last year? Or too soon to know?
And also, I agree with what Dsh said about what charity to donate to. I don't have any specific recommendations, but I'll go along with whatever the majority wants.
