We are currently in the process of updating our inventory tracking and category organization to provide a better shopping experience, but don't worry, we are still open for business. If you make a purchase and some, or all, of the items you purchased are not in stock, I, as the business owner, will email you personally to apologize and offer a solution that works best for you. Your patience during this update and upgrade process is greatly appreciated.
