Dial-up was horrendous.
Anyway, just checked DPD again:
"We have collected your parcel from the sender and it is now on route to you. If you check back on the morning of delivery you will see a 1 hour time of arrival for your parcel."
yay
They should email you the time slot too. I got a super exciting email from DPD this morning saying that they would be delivering an apron between 12:55-13:55.
