overspend!!!!!

[Midnitemo]

When I decided I would start prepping in earnest I set a budget of £100 per month....usually I'm pretty good with all things fiscal but somehow my spending has got away from me a little, in the five short month's I've been prepping I should have spent £500 but I have spent £871 without getting the calculator out that's about a 75% overspend is that how the start of prepping normally begins?...my new years resolutions are to check my overspend on the budget and get fitter.
