The first step to take in prepping is simply to increase the items you keep on hand. Most of us go to the grocery store every couple of days and only pick up whats needed for the next few days and only purchase dry goods such as paper towels and toilet paper when we actually run out.
The easiest step to take is to simply purchase items with a long shelf life in larger quantities and make sure you maintain at least a months worth always. If you don't already have a membership to one of the warehouse type stores, you should pick up a Costco membership right away. I recommend the Executive level membership as you get a 2% rebate on all your purchases. Simply put, if you purchase $5,000 worth of stuff from them in a year, you'll receive a rebate check for $100 which means a free membership. Since you'll be buying most items in bulk from them over the year, it will be pretty easy to hit the $5,000 mark in a year.
Tomorrow I'll share my list of items that I purchase from Costco and keep on hand at all times.
