(NEW YORK) — Each year, we spend time sweating over getting holiday gifts out in time and worrying about shipping delays.

This year, experts are warning of possible shortages and delays on getting everything from toys to artificial Christmas trees due to COVID-related supply chain issues, as well as reports of slower shipping service.

With that in mind, shipping services have released their recommended ship-by dates in order for packages to arrive on or before the Christmas holiday. The overall advice: The earlier you send, the better.
