Blowing a raspberry at the bill

Whilst working to become self-sufficient I have discovered that trading with other local food growers is an important activity. There will always be something they produce that I haven't grown, and vice versa. Our eggs, jam and honey often get exchanged for vegetables or fruit. It seems however that our trading system has extended beyond the sphere of food. My Land Rover needed a minor repair recently. It cost me 3 jars of raspberry jam. It would have been interesting buying the Land Rover with jam and honey though to do so, I would have needed considerably more hives that the 10 I have at the moment!
