I mostly do mystery shops but do a few revealed audits. I prefer the revealed audits as going through a check list is so much easier than remembering details. The reports are very easy. However , they take more time on the site.
And there aren;t many available where I llive.
Really, I have to try everything available to me a couple of times to decide if I like it and it it's worth it.
An example, there are so many people on here who Hate the Bed Bath and Beyond shops but I quite enjoy them. Doing one this week.
