Why I love Costco:
I had to be convinced to join Costco by my younger who had just moved out to his own apartment. He did a good job of selling me a membership but the card mostly languished in my wallet for several months. Somehow, though, I was infected by Costcolove.
This Gerties's Artichoke Tapenade is something I would never have tried for the price ($11+ for a jar) but Costco offered it to me for around $8 and I took it! We plowed through most of the jar in 1.5 days.
There's more, including their 2# tubs of Krinos Kalamata Olives (pitted, no less!) for around $6. I can't find them for less than $9/lb any where else. So yes, I'm in love. I visit monthly and would go more if it wasn't over the hill in another town.
