Allow an emergency purchase budget....
So that you can buy the thing you forgot....or left behind....
For example, last year for the first time I relied on my mobile phone GPS, great, but I hadn't realised it would run flat after a couple of hours.....just before needing it to find the 'Camping'
Went to phone shop in hypermarche next day to get dinky usb charger...16.90€...
Well worth it... cost versus benefit/quality of life....
Have fun
