The store card scheme is already instantly available to your existing Give as you Live supporters, there is no need for them to register. For new supporters visiting through one of your promotional links, they will be instructed to sign up with Give as you Live before being able to purchase a store card.
It is important to use the links within your marketing toolkit when promoting this scheme, this scheme is a closed scheme so people who are not registered with Give as you Live or visiting through your charity link will not be able to access the store cards.
Your marketing toolkit can be accessed through your charity admin system or via https://admin.giveasyoulive.com/toolkit
