I don't see organizations doing this as much as they used to, but this reminded me of a big "don't do this" for organizations.
The "Give us $5 instead of getting that cup of coffee in the morning!" is ineffective because people want their coffee (or whatever you're telling people not to get), let them have it! Also, trying to guilt donors into feeling bad for spending $X on something they like is *not* a way to make people feel good about your or your mission. Also also, you know what people hate more than anything? Being told what to do with their money!
Instead, try something like "Your monthly donation of $5 provides an Arkansan with _________ each month... WOW! Thank you!" It's donor-centric and isn't telling people what to do, but instead you're telling folks what cool things will happen if they donate.
Don't forget I'm available for hire if you want access to all the little Development nuggets rattling around inside my head.
