Friday orders may revert to Monday shipping. USPS freight does not move on Saturday even though post offices are open and deliver on Saturday.

Every once in a while, due to 3rd-party policies, address location, backorders, steep product discount, or other unique product circumstances, shipping may take 3-5 business days, or an order may be split into more than one package.

Order confirmations can take ~0-3 minutes before appearing in your inbox.

Orders to Short-Term Addresses (Hotel, Vacations, Airbnb, a Friend's address...):

When shipping to these addresses, please allow enough buffer time to allow for occasional shipping delays through USPS, or based on time of your order or distance from Arizona/Florida. If you are no longer at the address, instruct the residence to mark the package as "return to sender" or to forward it to your subsequent address.

Double and triple check that the address is formatted correctly.
