Attention - Shipping

The transition of our inventory to a new warehouse is taking longer than we anticipated. As a result, we are experiencing fulfillment delays and order(s) are taking longer to ship out. We are working hard to get the stock moved to our new facility as quickly as possible so that we are better equipped to meet your needs. We apologize for any inconvenience this may cause you.
