Refunded an order. I think they screwed up their shipping address. Also never replied to the email I sent letting them know that USPS returned the box and asking them how they'd like to proceed (I offered to either resend to a different address or refund the order). Given the lack of response, I decided to just issue the refund since I don't want to keep money for a product they clearly never received. Sent an email letting them know about the refund and reminding them why that was issued.
Maybe they'll try ordering again once they figure out what their address is.
