Does what it says on the tin!
I would certainly use My Hermes via Parcel 2 Go again. The site was easy to use, I got great comms from Karen at Parcel 2 Go.
My Hermes aren't the fastest but I was looking for cost.
I like the pre-pay idea, and the discount on that - but most of my stuff is small so Royal Mail are cheaper - when are you going to set up a cost-effective drop off service for small items, that would be ripper!
