The new Costco coupon rules are confusing. Some coupons come off automatically at the register without the customer having to do anything, others require the customer to present the actual coupons or have the smart phone app. Kimberly at Addicted to Costco has a clear write-up of the coupon rules; and, if you have questions, I recommend her blog post.
Using the new coupons, I'll be restocking the quart Ziploc bags, which have become our go-to freezer, lunch and travel bags; those have a $2.00 off coupon. I will be buying the Pure Protein Bars which are back on coupon at $4.50 off, and I'll purchase the Healthy Choice Fudge Bars at $2.80 off.
