Recently, I bought a new bow for my fiddle. I wanted to try a shorter than normal bow, to see if it was easier to use. I knew it might not work out, so I bought a cheapie from ebay. It was of surprisingly good quality, but for me the balance was wrong, so I decided to return it. The cost was £6.68 including shipping by Royal Mail. The deal was that the buyer paid return shipping. I wrapped it up in the original packing and took it to the Post office. They told me it would cost £10.40 ! I do not know what the seller paid in Postage, but it must obviously have been a lot less than £6.64, as otherwise, how do they make a profit. I put this to the PO staff but their attitude was take it or leave it. They said it was on account of the length. I pointed out that it was the same length as when I received it. Incidentally, I posted a tent recently, which was quite a bit longer and at least 100 times the weight. The postage was seven quid. Go figure.
