Do you guys have Aldi's out there? I don't shop at Aldi's, but have heard from a bunch of people that they have knock offs of all the GS cookies, that are better and cheaper than the real thing.

ETA: these are a little cheaper than what you found, and are supposed to be like Tagalongs https://www.amazon.com/Peanut-Butter.../dp/B00R7RNM8Q
