Looks like the only guarantee is NDD. Every other option seems to incur a delay

I think it entirely depends upon your area. Certain parts of the UK seem fine (I'm in the Midlands and First Class is working OK to other parts of the Midlands) others might take longer. I think it depends where you are and where your package has been sent from so I'm afraid its a bit of an ambiguous question.

Keep your fingers crossed.🤞

Cheers BB 😊👍
