I'm sorry to say that Amazon have increased their production costs for print-on-demand books such as Change-Ringing on Handbells. We have therefore had to increase the price from £20 to £25.50 for Volume 1, and from £25 to £33.50 for Volume 2. There are similar price increases in the non-UK markets.
This is a very large increase but there is nothing we can do about it, unfortunately. The prices of the Kindle editions are unchanged at £8.99 for Volume 1 and £9.99 for Volume 2.
