DPD

Unlike the other couriers so far, DPD hasn't provided a 'last postage date' for UK shipments, they're closed Christmas day and boxing day and that's as much as they've said about the topic.

I'd advise you to contact DPD directly if you're concerned whether or not your shipment will arrive on time.

As for international shipments they've provided a long list of dates sorted by country.

You can find the list of international postage dates here


UPS

UPS has provided some rough dates for a few services, but they've also provided a handy cost and time calculator which will tell you when your shipment will arrive by and how much it will cost depending on the service and date you send it by.

Calculate Time & Cost

Here are some of the date's they've provided.

Monday 18th December

  • UPS 3 Day Select®

Wednesday 20th December

  • UPS 2nd Day Air

Friday 22nd December

  • UPS Next Day Air
