I think I saved about £10 using paisley over parcels2go on a very large bath.
also worth checking their prohibited items list. I don't know what your sending, but they can just bin your parcel if you send something that's on the list.
paisley were cheaper than parcels2go recently on a very large item I posted. and it was still TNT who came and collected it.
shop around do the quote function and work from there.
most of these companies are third parties that have deals with the main couriers. and sometimes companies that are cheaper on small packages don't have the same deals on the larger packets.
where in the UK are you?
I have a couple of lathes; but access might be an issue as they will only be available at certain times. and getting you on site may not be straight forward.
one of my colleagues lives in Felixstowe, he got a call from his wife the police have just been round and told they have to evacuate the area. had to leave early to do what he can before 6 pm when they were shipping everyone out.
