The charity has mounted a press and PR campaign to exploit the link-up while Superdrug will promote Macmillan through public awareness messages on pharmacy prescription bags.
The deal, which is expected to last for at least a year, will see Superdrug staff from the 700-store network help promote awareness of the charity’s work.
Macmillan head of corporate fundraising Edward Hodgkins said the partnership opened up fresh comms opportunities.
He said: ‘Through working with corporate partners such as Superdrug we can broaden our supporter base and work together with the company to fulfil both its fundraising objectives for the partnership and our communications aims.’
Macmillan replaces Breast Cancer Care, which earned more than £1m from fundraising following a similar arrangement with the high-street retailer.
