Yes, the idea has come up. But the logistics of making sure that vendors who put a way to donate to CASAA on their site at checkout actually are turning the collection over to CASAA is overwhelming - meaning, there is no way for CASAA to vet every vendor to assure people that their donation is actually going to CASAA. So, I believe it was thought it would be better to just have vendors redirect customers directly to the CASAA donation page. It be great if they would put a link to us on their final purchase confirmation page!
