Looking through my bookmarks for ideas for the YDC Facebook page and found this one:
http://www.easyfundraising.org.uk/
"Raise money for free when you make purchases online.
We've partnered with over 2,700 online retailers who will make
donations to your chosen good cause when you buy
from them.
The donations come from the retailers, not from your
pockets and it's free to use."
Has anyone used them for shopping/donating?
