I've been shifting a load of parts lately and I'm sure a lot of people who use the classifieds regularly to sell stuff will have noticed that Royal Mail has jumped their prices up so much that they're rarely the cheapest option anymore. I think a lot of people know that Hermes are the cheapest for most stuff.
Well, there seems to be a reason for this- I had a parcel turn up in February from them that was smashed to pieces. I hoped this was a one off, but in the last month I've sent out 8 parcels and 2 have turned up damaged and one has been lost. People that've bought stuff off me get hacked off, I'm down on a few quid until they sort it out. I've NEVER had a failure rate like this before.
I know a lot of people have found them fine but I think this failure rate is a bit high, so use with caution IME.
