Jill Chatwin has set up an account with Easy Fundraising.
The web address is
http://www.easyfundraising.org.uk/
You just have to register (its all free) and then pick the cause you wish to support (that is easy - there are only two listed for Llanteg - the Hall and this one!).
You then use their search facility whenever you make a purchase online, and a small amount is donated to Community funds.
