Holiday Shipping


Dear HST Customers,

We know it’s important that your holiday gifts arrive on time! While we can’t control what happens once a package leaves our warehouse, we can promise you that we’ll work hard to ensure your order is packaged with care and shipped out our doors in a timely manner.

Take a look below for help determining when your order from our warehouse. For the most accurate estimates, we recommend using the “Estimate Shipping” tool in your shopping cart. A few tips to keep in mind:

Shop Early – The sooner you can place your orders for the holidays, the sooner we can get the package out the door. If there are any unexpected delays with couriers, there will be buffer time for the arrival of your order.

Back Orders – If an item on your order is on backorder, it will be clearly stated in your order confirmation email. Please reach out to us at [email protected] if you have any questions regarding your order.

When you give a science gift, you’re also gifting wonder and lifelong learning. We’re thrilled to be a part of your holiday planning.

We wish you a wonderful Christmas season!
