To preserve our margin for The Rotary Foundation, it has been necessary to increase the bottle price to £25 wef 1 April 2011. We resisted a price change on 4 January last when VAT increased to 20% but, as a consequence of the Budget on 23 March, the price increase from 1 April is regretable but unavoidable. We hope your customers will appreciate the circumstances here and our desire to maintain our margin to help the final push to readicate polio worldwide.
