I'm trying to sell a very large painting - the parcel will be about 150 x 100cm x 25cm thick. I did list this as 'collect only' and have had a potential buyer asking me to post. He has told me that parcelforce 'large parcel' should be around £15 for this (hate it when buyers tell you how to pack and how much to charge!) My checks on parcelforce come out to over £40 for this size. Can anyone recommend a good service for paintings? (It has a delicate frame and glass) It's not hugely valuable (probably won't sell for more than £40 unless I'm very lucky). Thank you
