National Shopping Service is a fairly new mystery shopping company to me but I find the shops easy to schedule and the reports easy to complete - both a bonus in my book! There is a good variety of food and retail shops near me and I like how you can indicate you are interested in a shop even if it has already been assigned to another shopper in case they can't complete it.
I found the directions for the shops to be very clear and loved that minimal narrative was required. The shop paid adequately and I will definitely be doing more shops with National Shopping Service!
As always, it's FREE to sign up to be a mystery shopper for any of the companies I blog about. You can read more about the mystery shopping companies I blog about here. Please read my Mystery Shopping 101 post for more information.
