The British Heart Foundation hopes to raise £150,000 with corporate partner Flora from an on-pack promotion that involves giving away charity Christmas cards with purchases.
Throughout November, special 500g tubs of Flora pro.activ margarine will come with a complementary pack of five British Heart Foundation Christmas cards, as well as a leaflet showing the charity's top tips on how to maintain a healthy heart.
Flora will donate 15p to the British Heart Foundation for each of the special tubs sold.
"This is another great way that the public can support the British Heart Foundation, as well as helping to increase the public's awareness of our key heart health messages," said the charity's head of fundraising, Douglas Rouse.
The promotion is also set to raise the profile of the charity's Christmas cards, which are available online at www.bhfshop.co.uk.
