Our main goal is to provide families with science materials promptly and inexpensively. To meet this goal, we can't ship large-quantity orders ahead (usually for more than 15 of one product) if they will deplete our inventory and cause an extended delay for other customers.
Can I place an order for large quantities of an item?
We will fill your large-quantity order as quickly as possible, but we cannot guarantee that it will ship immediately. When ordering large quantities of a product, we encourage you to order at least 4-5 weeks in advance so we can meet your needs in time for your project. Please give us a call at 1-800-860-6272 if you need any assistance; we're happy to help.
