Shipping, Returns & Refunds

Turnaround Time for Orders

On average, orders are processed and shipped within 3 business days from the time that they are received. When items are unavailable or out of stock, shipment may be delayed until all items are in stock. A member of our customer support team will contact you if there are back orders or other delays.

If you have an order or are in need of expedited shipping, call (800) 780-9126 to place your order by phone, and we will gladly inform you of current availability and shipping options. Orders placed online may not be processed until the following business day, so we encourage customers to call us with expedited concerns.
