We are moving into our new warehouse! This is a huge project, and as such, we are unable to ship orders (including expedited orders) placed 9:00 am MST January 8 through 12:00 pm MST January 26. We will resume shipping January 26, and orders placed Jan 8-26 will BEGIN shipping at that time. Please allow several additional days for us to catch up after our move.
