I was going to sell some of my unwanted campingaz canisters on eBay but I wasn't sue whether I can post them. Do they have to be packaged in a certain way or have certain warnings on the box?
By Royal Mail it's a real no, no! When we moved house a couple of years back the removers - Pickford's - refused to take anything connected with our camping stoves including the stoves themselves plus the gas. So I reckon couriers or other carriers would take the same stance. I would take knownout's advice and flog 'em at a boot. Even if you don't have a stall you could trade them with one of the merchants.
