At this time, the website is experiencing slow performance for shopping carts with more than 40 line items. If you are building an order of more than 40 items, we recommend breaking the order into 2 separate quotes/orders that use the same PO Number. Our customer service staff will happily combine your orders into a single order for volume discounts and billing, and is available at (800) 322-3247 to discuss any questions you may have Mon-Fri 8-5 Eastern time.
