i do not have a costco card. i really can not justify having one. seriously do i need 20 a pound bag of flour or a pack of 50 batteries? no. however, i will not turn down an opportunity to accompany a friend on a little costco outing. 2 large jars of nutella later + i am thinking i might need a costco membership after all! heaven.
ps: my favorite costco in the napa valley area is the fairfield location. super clean + lots of organic options!
