You know, some of the people who use the service would love to have extra userpics, but are poor college students.
Just to put a bug in your ear - it would be nice if you could have offers like 50 extra for $10 or something...and maybe you can include that as a different sale in case you want to raise donations for the shelter in the future.
My heart goes out to all those people caring for those animals. I hope some people come out and offer to adopt or foster - now would be a great time.
I can't afford much, but I donated what I could - softy and big animal lover that I am.
