Dont know if this has been brought up but easysearch.org.uk and easyfundraising.org.uk is very good i know a few local schools and clubs close to me that have used them to raise money and have rasied a fairly substantial amount of money.
You can raise money by seaching the internet with easysearch (I admit its hard to make that switch from google) and shopping through hundreds of online retailers including Amazon, ebay e.t.c. and the organisation in question recieves a percentage of the purchase price.
We wouldnt be able to raise money for the club directly (id imagine) but the supporters trust/supporters club would be prime candidates. (as an organisation)
