This is pure speculation on my part, but is there some sort of psychological trick that we are playing with ourselves here? Like we oversell the 'benefits' after we've paid the membership fee, to avoid feeling like we made a bad purchase? Sometimes I wonder if I do this with Amazon Prime.
The reason I bring this up is because I actually laughed out loud when you guys were posting about the quality of Kirkland stuff. Its all highly processed food. I've become really polarized lately when it comes to food, and how we consume it, so I'll admit I'm sounding (as per usual) like a pompous douche, but the idea of buying their food just does not seem like a very good idea.
Also, I say this as a former employee of the White Marsh Costco....they didn't treat me all that well, and one of the managers was a great friend of mine.
