Amazon is convenient. But multiple times recently I've discovered stuff; ordinary stuff, cheaper elsewhere.
Example today:
Patterson & Ilford Film Processing Starter Kit
£99.00 on Amazon
or you could go (as I did) to a non-gigantic behemoth company, Bristol Cameras, who are literally a camera shop... in Bristol, and pay £81, including delivery, for the exact same item. And give the business to a small firm who might possibly appreciate it.
