However, not all Costco shoppers agree with the stellar reviews of Kirkland Signature bacon. In fact, there are a few dissenting voices from reviewers who left comments on the Consumer Affairs site. One consumer wrote in November 2019: "The outside package is good, mostly meaty, but as you go further inside, it becomes white fatty, and slices are becoming so thin and cut small, that I can't properly cook them without them being burnt. Almost like a bait and switch." 

And the problem with hidden fattiness seemed to be fairly common. In a separate post dated October 2019, another consumer commented: "Looked through the packages and found what seemed to be a good looking pack. When we got home and opened the package, we noticed [two] slices weren't sticking to the others, and when we peeled them off, the rest of the package was totally different than the [two] slices. It was almost all fat! Totally deceptive packaging and a total disappointment in Kirkland Signature."

The bottomline: If you select a good package, you're sure to have the tastiest bacon at the best price — just try to choose wisely.
