Easy Fundraising
Easy Fundraising gives a percentage of what you spend to the MSA. You can download the app or a browser extension from https://www.easyfundraising.org.uk/ and when you shop online MSA receives funds. The donations range from a small percentage for things like a weekly grocery shop to cash sums of £50+, for occasional purchases such as phones, insurance or holidays. Easy Fundraising partners with all your favourite retailers too, so do please make the effort to go there first when it is time to purchase gifts.
