After chatting with some people on Discord they convinced me to be bothered to return the broken mouse.
They explained that since it was so cheap, the refund would be issued immediately.

They were wrong, but wait a minute … £9.36?

I paid £4.37, that was the whole point – get cheap mouse, and also why I couldn’t be bothered returning it.
But if I’m being refunded more, well alright then. There’s a returns box in Morrisons, it’s quite good and must be a new thing. Last time I did a return it had to go to an Evri dropoff point.

I bought this amazing device instead. It’s fine… The Bluetooth is laggy, but the wireless dongle works well.

So to recap…
- I got a £25 Amazon gift card code for trialling a new app for charging my car
- I spent £4 of it on some e-waste
- I returned the e-waste
- I got more money than I spent as a refund
- The mouse was probably someone’s old mouse that had failed, and they probably did a shady switch after buying a new one and returning it.
I wonder who will get it next 😄
