Since members of this forum have savaged another shopper who self-published a book on mystery shopping for trying to make money off of shoppers (Equating buying the book with "paying to shop," as I recall.) I doubt that Flash is likely to be enthusiastic about such a venture.
However, I will defer to her on the subject.
