I'm sure many of us shop on amazon and we can make 1/2% go to USARK at no cost, there are plenty of smaller reptile groups available to donate to, but wouldn't USARK be a nice one to funnel some "free" money into. I already sent them an email about it. Once they sign up we would just need to change our charities to them and never think about it again.
