Keystone Supplies shipping policy
Effective October 1, 2026.
Where we ship
We ship within the United States only: the 50 states and Washington, D.C. Checkout accepts US addresses only. We do not ship internationally, and we do not currently ship to US territories or to APO, FPO, or DPO addresses.
Handling time
Every order is packed by hand. An order leaves us within 2 to 4 business days after its payment is confirmed. Business days are Monday to Friday, excluding US federal holidays.
Carrier and delivery time
We send orders by USPS Priority Mail with tracking. USPS estimates 1 to 3 business days in transit for Priority Mail. That is the carrier's estimate; we cannot promise a delivery date.
Shipping cost
There is no shipping charge. Checkout does not add one.
Tracking
When your order leaves us, we email the tracking number to the email address on your account.
Address problems
Check your delivery address before you pay. If it is wrong, email us before the order leaves us and we will correct it.
If a package comes back to us because the address entered at checkout was wrong or incomplete, or because it was refused or not collected, we can send it again once you pay the new postage, or refund the order as described on the refunds and returns page.
Lost packages
If tracking shows no movement for 7 business days, or shows the package delivered but you do not have it, email us. We open a claim with the carrier and send a replacement or a refund once the carrier confirms the package is lost.
