Hello! I am new to secret shopping so please explain - With the membership shops that require 1900 sku scans, how do you stay undercover and remain in the store for that length of time (I assume it takes at least a few hours) without being questioned? 

Any assistance you can provide on this type of shop is greatly appreciated.

All of that information is covered in the certification process, but the shop can be done over the course of a few days, and does not all need to be done at once, so it can be broken up between those days.

The store doesn’t usually pay attention, at least not in my experience.
