Hello all, I am new to all of this, but want to become prepared for an emergency situation, and have been stocking up on supplies for a few months now (it only took me and a few years and Jericho to convince my better half!). Is a Sam's Club/Costco membership worth it? I would only be able to get to one of those stores 2-4 times a year. I heard that if you do not go often enough they will revoke your membership and make you re-up. Is this true? And are the prices good enough to warrant purchasing a membership? I will greatly appreciate any advice.
