As I live on an Island Royal Mail and the Manx postal authority are an important link to the outside world, in this I can say the service on both counts have been very good, I recently tried to post some spare tx batteries to a friend in the uk, but our post goes by plane so were not allowed, (aviation rules),the cheapest I could get by courier was £18, this was for 2 x 8 pack AAs in a jiffy bag, and that was depot to depot, not depot to home address, so I asked the girl in our local post office to give me a price if posted within the uk, £1.84, so I found a friend who was travelling by boat and showing him what was in the envelope, (He is a model builder), asked him if he would drop it in a letterbox at his destination, this he agreed to do, the jiffybag and contents arrived two days later, so comparing courier to RM is not a realistic option.
