For large volumes of certain products (i.e. greater than 6 copies), be aware that additional lead time may be required to obtain additional copies from the supplier. There could also be opportunities for volume discounts for larger orders (> $500) when these are requested. We suggest that you contact us prior to placing an order for any order greater than 6 copies so that we can best accomodate your order within adversely impacting our other customers. We can usually provide some incentive or discount for doing so.
