HirschMusic Publications has graduated from blog-style-paypal-buttons to a full-fledged eCommerce storefront. It's powered by Volusion, which has been in that biz for a decade. The transactions are secure and easy.
It's a soft opening for the moment while I tie up final loose ends, which will likely take a few weeks, off and on. That said, the download store is fully functional (until someone points out the parts that don't work quite right) and ready for action.
