Hey, everyone. Have you heard of Amazon Smile? Basically, Amazon will donate 0.5% of an item's purchase price to your chosen charity every time you shop with them. I'm currently banned (self inflicted!) from online shopping, but have set it up on my account, with BHF as my chosen charity, for when I next succumb to online temptation and buy all the books... Bound to happen eventually.
It was very easy to set up, but the full details are here - smile.amazon.co.uk/gp/chpf/...
(Hoping it's not an elaborate tax evasion scheme... Ha!)
