Stay organized and read your assignments thoroughly. I have a couple of calendars that I use and a whiteboard. Most of all - have fun! Mystery shopping is a great way to earn passive income and help companies with feedback and quality control. It's win win!

I find I can't turn my "mystery shopping eyes" off even if I am not doing a shop. I find myself quickly glancing at the cashier/salespersons name tag, asking for a receipt, noticing things, etc and then I realize I am not doing a shop! You become so well trained with your eyes and ears, it just becomes something you normally do. Not a bad thing though!
