CostCo is the greatest store ever.
I saved 40% on a 20 pack of Vitamin Water, walked out with a 10lb bag of pancake mix, spent almost nothing on 40oz of mixed nuts, passed on a 3lb box of Wheat Thins, and paid $6.50 for 12 muffins that are bigger than my head (not quite, but they're damn big).
Oh! And free samples at the end of most of the aisles!
I was like a kid in a candy store – literally, when I went down the candy aisle.
