This Costco ad is all about the Christmas holidays. There’s several trays of cookies and gooey cinnamon rolls. There’s a shrimp cocktail that’s perfect for a holiday party. We recently learned that the Kerrygold Reserve Cheddar is pretty mind-blowing, so we’re excited to try it at $3.30 off per package. If done right, the Just Bare Lightly Breaded Chicken Breast Chunks are fantastic, rivaling some of the best fast food fried chicken you can find.
Some items may not be available at all Costco locations. Pricing may vary by location in Alaska, Hawaii, Puerto Rico and online. Which items stand out to you in this weeks insider deals? Leave a comment and let us know!
