I have no idea how to offer in-store credit. But it still remains a logistical nightmare even if others are doing the xml. I still need to vet/QA and implement the LOS into older products and it really is not something I have time to do or manage others doing. Seriously, I have a dozen projects besides Meanders and I study at University, I'm learning Mandarin, making several RPG and card games, managing Kickstarters, my website, facebook groups, twitter accounts, and just doing what I'm doing is already a tightrope.
