Is your school or office limited as to when it can receive goods?

Ordering multiple, heavy-weighted items?

Sorry about that.
Just contact us by email or phone and we'll figure out another way to get your order to you.

Order processing time depends on availability of the product from the manufacturer, but typically products are shipped within 10-15 business days after the order is placed. See shipping options for the number of days it will take to reach you after it leaves our warehouse.
