As mentioned in another post tin has gone up in price, when we started to cast KA low was around the £25 a kilo last time I brought it was around £35 a kilo that was 6 months ago, now the same supplier it's up to £78 a kilo, so as you can see the price has doubled and then you add post it is getting expensive ( I have look around but this is still the cheapest) to make figures so bear this in mind when you next order
