Have found some banging bargains in charity shops, best of all time an ultralight tent for backpacking (my hobby) and the best this (2023) year was a Rab jacket. Best tip is to visit nice towns for the day and check out the charity shops whilst there...
I like GPS and GPS Mapping apps because I'm into hiking/backpacking/wild camping. I'm an old crumbly so I don't need the latest and greatest tech tbh, as long as the GPS works!
