UPS SHIPMENT ALERT

Due to the tragic UPS plane crash in Louisville, KY, some UPS shipments--including expedited packages--may be delayed. 
Our thoughts are with those affected by this incident. Thank you for your patience!

Any orders placed after this time will be processed on Monday, April 21st.
Have a happy Easter weekend!
