I needed a replacement camera battery. It’s £5 on the high street but just £2.16 online (with free delivery). It’s the size of a 1p coin and I was expecting it to come in a jiffy bag, delivered by the postman, through the letterbox. Instead, it came by courier van in a big box. I can’t see how this can be profitable for the supplier…

And I ordered the wrong battery, so I have re-ordered the right one, in another big box!
