Good Evening Lynda,
My name is Colleen. Though I am new to iSecretShop I am not new to mystery shopping. The best advice I can give you, is to choose shops that you normally would do anyway. If you go to Jack in the box for dinner then go there for a shop. It will help you in being more normal and unidentifiable as a secret shopper.
I found new places to shop this way. So now when I do a shop I actually go and purchase clothes and its natural. They now just know me as a regular customer.
I hope that helps with your question.
Colleen
