A couple of weeks ago I lost my car keys while walking my grandson across the South Downs. This was very upsetting, partly because I never lose anything and more so because a replacement key for my Smart was going to cost £135 and for the Astra £100, plus my house keys. Imagine my delight when the keys were returned by special delivery today. My keys carried a tag from Sentinel card insurance that invites you to freepost them back to Sentinel who then forwarded it to me. My premiums with them have been good value for this alone. Also, a BIG, BIG, BIG thank you to the kind and unknown person who picked them up and dropped them into a letterbox.
