Most orders ship the same or next business day. When your order ships, your tracking number is emailed from order@primescience.st. If you haven’t received it within 1 business day of your order confirmation, check your spam folder, then contact us with your order number.

You should receive an order confirmation from order@primescience.st shortly after checkout. If you can’t find it, check your spam folder. If it isn’t there, contact us with the name and email address you used at checkout before ordering again, so you aren’t charged twice.

We ship within Canada only, with Canada Post, in plain packaging. PO boxes and Canada Post FlexDelivery addresses are supported. Most orders arrive 2 to 3 business days after you order; remote and rural addresses can take longer. Shipping is $20, or free on orders of $200 or more. There is one shipping speed for all orders.

Contact us as soon as possible with your order number and the change, including any missing unit or buzzer number. We can change or cancel an order only if it hasn’t shipped yet, and because most orders ship the same or next business day, we can’t guarantee it.

If tracking shows delivered, check with your household, neighbours, building front desk and community mailbox, and look for a Canada Post delivery notice. If you still can’t find it 2 days after the delivery date, or tracking hasn’t updated for 5 business days, contact us with your order number. We’ll look into it with Canada Post, and where a parcel is confirmed lost, we may reship it at our discretion.
