It soon adds up .
But all these are vary diverse between us all .
Indeed the expenses can be diverse. Some years I won't spend a penny on work clothing. Other years I might buy enough for two or three years if I see a good deal.
Same with poles. I will go on for a while replacing poles and spending money on them. At the moment, I am repairing old poles from my graveyard, glueing clamps, sawing ends off poles to re-clamp, removing threads from the ends and making repairs. I reckon I've got so many old bits and pieces of poles, they may well last me a couple of years. A few hours work on a stormy day can save me a fair bit of money. For pity's sake, I've even got an ancient 15ft Ionics glass pole which will do for some jobs at a push.
In the past, I've just bought new poles.
My two work fleeces I've had for several years. They aren't used much - just in the harshest weather.
However, some years I may end up buying lots of clothing and a more expensive pole or two, replace broken hose reels etc.
It fluctuates wildly.
