panic buy it all now or wait?

[Midnitemo]

I've always been interested in survivalism/preparedness(Be Prepared,is my football teams motto lol)but with a feeling of impending doom starting to wash over me i've just begun to act hence joining this forum , The forum has been a real eye opener in terms of opinions insights and some great advice , my concern is everyone i've mentioned prepping to thinks i'm stark staring mad , partner would hit the roof if she saw my little list i've compiled of essentials that i feel need immediate attention , i reckon i could spend 3k tommorrow on stuff i feel i need right now but my availabe budget is perhaps £100 a month tops , the question is do i borrow money to fill the crucial inventory or do i gamble on nothing happening for 30 months til i've accumulated this essential stores?
