As a single man with no kids I don't use Costco. However if I were you, I'd make sure I have a month worth of food, water, supplies, etc. for when shit hits the fan in November and then dump Costco. I have been tempted to get a membership for a month just to stock up but I've managed pretty well without Costco and have not done a cost benefit analysis. I think we have an obligation to vote with our wallets and I try to. In fact, there are some things on Netflix I am really excited about upcoming and I dumped them anyway two weeks ago.
