Stop Boots over-charging for vital health treatments

Challenge Boots the Chemist to charge fair prices for vital treatments, including a mouthwash needed by cancer patients undergoing chemotherapy.
There are reports that Boots charged the NHS £3,220 for 600 ml of the medicinal mouthwash, which costs only £93 from a pharmacy in West Sussex for the same quantity. If true, this is shameless exploitation, and is unworthy of a retailer which has hitherto been a trusted high street institution.
