We currently only use Royal Mail or Parcelforce tracked and signed courier services for most of our shipping methods, although on occasion we may use DPD or other couriers even when this is not indicated at checkout. Exactly which of the various courier services will be used depends on numerous factors.
These factors are related to the size and weight of your order, and your location globally.
In most cases locally in UK we will use Royal Mail 48 hour tracked deliveries, or normal Royal Mail First Class.
For international shipments we typically use Royal Mail International Tracked or Parcelforce Worldwide Global Express.
