Just for a bit of balance....I've always found Hermes/Evri to be exceptional. Sold my car a few months ago, but before doing so, I took off some of the aftermarket bits and sold them separately via owners groups/forums. Evri have a drop-off point at the local Co-op, half a mile away. So it was just a case of entering the address and paying online, walking down the shop with whatever I was sending packaged up, printing off the label using the code emailed to me, sticking it on, handing it to the cashier, and getting a receipt with a tracking number. I must have sent 7 or 8 parcels, and every single one of them arrived as intended on time, and in some cases, quicker than expected...even when not paying extra for the next day services.
Never had trouble receiving parcels sent by Evri either. It's the same courier every time, so he evidently works our area...always polite, friendly and turns up exactly when predicted by the tracking. I can only think that the service level is regional and dependant on who your local courier is.
