Holiday Shipping


Dear HST Customers,

This holiday season is projected to be one of busiest seasons yet for online orders and shipments. We are taking proactive measures to help ensure your shipments arrive in good time – especially your items being gifted under the Christmas tree.

With this in mind, we wanted to encourage the following:

  • 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 package(s).

While shipping providers are doing everything in their power to avoid delays, we wanted to make you aware of some updates:

  • UPS – has suspended their shipping guarantees for all services except next day air. This suspension has been in place since March 26, 2020.
  • USPS – this is not an expedited method, and delivery dates are not guaranteed.

We’re in close connection with our couriers and keeping a pulse on their updates. They are doing their best to ensure on-time deliveries and we wanted to support you by sharing this information and encouraging early planning.

With science, you give the gift of wonder. We are thrilled to be a part of your holiday planning and helping to create magical memories for your family this year.

Merry Christmas and Happy Holidays!
