I was given a hand held GPS unit for a Christmas present. It worked well, but it's maps were out of date. To get the latest maps on CD I could go to the U.S. manufacturer direct or pay the sterling equivalent of the same price from the U.K. importer. One of the CD's had only just come out, but the unit was soon updated. Then it fell over the side of the boat (s**t) didn't it? Thus I had two new, useless but highly expensive CDs. I put them both on eBay. The first, slightly older disc sold for about 20% more than I had originally paid for it, again on eBay. The brand new disc, acquired from the U.K. supplier for £120 went for £140 and the buyer could have obtained same by return of post, carriage paid for the said £120!
