USPS Priority/First Class Mail

• Delivery Time: Usually 4-10 business days via US/Canada postal services.
• Shipping Charge: Actual weight-based Postal Service shipping charges. This amount will be provided after you enter your shipping address during the checkout process.
• Restrictions: This option is available only to Canada. Living items starting with "LD", chemicals starting with "UN", and preserved animals starting with "PM" cannot be shipped with this option. Our drop-shipped microscopes (the Lab and some digital models) cannot be shipped to Canada, either.
• Note: Shipments sent via this method are not trackable.

Backordered items: We may hold orders for up to seven days if out-of-stock items are expected within that time. Otherwise, all in-stock items are shipped immediately, and backordered items will be shipped separately by the least expensive shipping method when available. We usually ship backordered items within three weeks. You may cancel backorders any time up to the shipment date.
