I love the Shihjr Costco. I am convinced that they have a better selection of products than the Neihu Costco. And they've introduced some new ones recently...including...
Nature Valley Fruit Twists---which look like a grown-up fruit roll-up to me.
Icee Squeeze Tubes
Several varieties of Weis ice cream. (An Australian brand...GOOD STUFF)
The best dark chocolate and pomegranate ice cream bar on the planet.
Large bags of protein shake mix in both vanilla and chocolate flavors. We tried the vanilla, and it's good stuff...mix in a few frozen blueberries, and you have a low-calorie, high-protein blueberry shake.
And taco shells! No more driving to Tianmu and hoping that they're not stale inside the box. At Costco, you can get a big box of 48 taco shells, packaged in four different bags. They last well in the freezer.
