Anybody joined Karl's Klub? I'm wondering if it's worth joining, how much it costs to join, do you feel like you saved money by joining, and if you have to pay "dues" every year? It seems like a Costco sort of arrangement, and I don't belong to Costco. I'm wondering if "being a club" is a valid way to skirt around the manufacturer's mandated selling price...."Bob's Your Uncle", etc.
