YES WE ARE HERE FOR YOU!!!
With increased sales/demand for our products and the Covid induced workforce challenges and supply chain challenges... we're working hard to stay on top of things and take care of you! We are here to answer your emails/calls. We are shipping every day. Most orders ship immediately, though some of our higher demand products may take a few days. In some cases we're telling people two weeks, then working hard to surprise them when it arrives in a few days (80% of the time we can do that). We've added a new tech support person recently, and we're currently hiring for production, order processing, and shipping positions so that we can serve you even better! We are taking care of 20+ families while busting our tails to take care of you all, and we greatly appreciate you letting us serve you. THANK YOU FOR YOUR SUPPORT!
