@thamesynne Hermes is fucking awful - I used them briefly when I first started my business because they were a few pence cheaper for larger items than Royal Mail.
When I dropped stuff off at the "parcel shop" (aka Bargain Booze) it took 2-3 days for it to even be *collected*. I had nothing but complaints.
Since switching to RM for everything except massive stuff (I use ParcelForce for that) I have had 5* reviews on delivery and no complaints. Skimping on delivery is a short-term view.
