PLEASE NOTE: As a result of the planned industrial strike action impacting Parcelforce services on Friday 30th September and Saturday 1st October 2022 we are expecting some delays in deliveries which may mean that not all orders are received “next day”. Despite our very best efforts it is inevitable that there will be some small delays outside of our control and we appreciate your understanding. Thank you.
