I agree with Tolik….. I picked up a second job to buy what I felt that I actually needed. This included a lot of firearms, ammo, equipment, fuel storage, hand grinders/mills, etc….
Now that I am caught up I am getting ready to quit the second job and get back to building things.
The reason I had to get a second job was because my normal expenses were higher than what allotted me the ability to purchase what I thought I needed in a timely manner. What I suggest is that you do what you would do if you were putting back for a down payment, vacation, etc. Just find a percentage to save from each check, make a list of what you need, and then get the items as you see good deals. It all really depends on how much you feel you can put part with from each check.
