The Post Office has partnered with parcel company Evri to sell delivery products outside of Royal Mail for the first time in its history.It means that people will be able to drop off and pick up parcels through Evri in some local Post Office branches.The tie-up will be trialled in 50 Post Offices before Christmas, where customers can find an Evri ParcelShop self-service device within the branch.Post Office – which has more than 11,500 branches – said that it marks the first time in its 360-year history that it will be selling products for end-to-end delivery with a carrier that is not Royal Mail.It has struck deals with three other big carriers in the past year – DPD, DHL Express and Amazon – to roll out click-and-collect services, whereby people can order items online and pick them up from a Post Office branch.
