βKey Takeaways
The first time I walked into Costco after my celiac diagnosis, I almost cried. Endless pallets of giant muffins, croissants, and bread β none of it safe.
That was three years ago. Today, Costco is my #1 grocery store. Once you crack the code, Costco has one of the best GF selections in the country at prices that make Whole Foods look criminal.
