We use different delivery services depending on the size of the parcel.
Royal Mail: A calling card will be left and your parcel will be taken to your nearest post office. It'll then be held for a number of days, which will be stated on the calling card, for you to collect (remember to bring proof of ID).
Yodel and DPD: A calling card will be left and you'll be given the opportunity to arrange a new date.
Yodel, ArrowXL and BJS: You'll receive a text the evening before with a time slot the couriers will be arriving. You can re-arrange at this point. If the delivery were then to fail on the day, the parcel will be returned to their warehouse and you'll be able the arrange a new, more suitable day.
In all cases we would advise you to try and be in on the original delivery date, so your items don’t stay too long in transit and you can enjoy them as quickly as possible.
