I have a love hate relationship with Amazon. Blood convent but devious money grabbing tax avoiding..

Etc.

Anyway.. if you want to support a charity use https://smile.amazon.co.uk/gp/chpf/homepage?orig=%2F

I've been supporting a kidney charity, but the dropdown menu has a good fair few charities listed.

Doesn't cost you any more, or less. And to be honest I've found some Amazon stuff a rip off and cheaper on eBay or an independent shop online.!
