Ayup, had a second class signed for parcel containing a tweed blazer sent on the 17th December second class signed for from west to south Yorkshire, hasn't been delivered and it's now the 2nd of January. Funnily enough I had two other second class items dispatched after the 17th and delivered a few days later from the other side of the country, so I'm confused as to why this one has seemingly disappeared even though it was the one closest to me

.
Is it normal for second class to take more than two weeks at this time of year or should I give up and consider it lost? it wont be a small parcel so don't know how it could get lost, unless the label fell off or something. I didn't choose for it to be sent second class the seller chose that themselves so not very happy with them. Is it likely that it's just in a York somewhere and tracked parcels are still being given priority?.
Thanks
