I joined a little over a year ago in large part to get glasses. Didn't go so much at first but have been going moreso of late.
I only get certain things there, I won't sacrifice taste for value, so something like Salsa which I do eat in bulk, I won't buy there because all they have is some wimp ass mild mango salsa or something. I do get paper products like TP there, and gas, got regular today for 3.15 a gallon which is the best around. Can't beat their prices on almonds and Walnuts. And lately every time I go I get a pair of pants, shorts or shirts. Really good work pants for $20. Shorts for $15.
And at the end of the year you get money back, which this year I hope will fully offset the membership fee's.
