Some of you may know of this already but I am recommending it because it's a new discovery for me: Easyfundraising
You register with the site and pick your charity. I have picked Tia Greyhound and Lurcher Rescue
but there's a wide range to choose from and you can even register a new one.
Now, when you want to buy something online - and again there's a massive list of choices including Amazon, Tesco Direct, Waterstones, P. C. World, etc., etc., - you go through the Easyfundraising site. Then a small percentage (it varies) of what you pay for your purchase goes to your chosen charity. There's no cost to you.
Potentially this could give your charity a lot of money over the year without costing you a bean. Great idea, I thought.
