ITA, but I think the point is in one case I was buying something that I wanted to buy and the fundraiser benefited, in the other case I was asked to buy something I did not want to buy at that time. Using the book sale. I want to buy book X and they have it, I get it and we are both happy I have my book they have their money). I go and want to buy book X and they don't have it, do I need to buy book Y (I don't get what they want and they get their money) or can I just leave empty handed (no different than my not showing up)? Does that make sense?
