Hello, I want to share my little experience with mystery shopping. I suscribed with them 2 months ago and very few tasks are available. Last time, they had on offer: you go for lunch time at Pacini.You have to stay there for one full hour and order a complete meal. You have to visit the bathroom. Then you have to come back home to fill a 2 pages report. Compensation: 5$ + they refund you max 10$ for the lunch.
I'm sorry but I think this is ridiculous. Just the gas will cost more than 5$. And ONE FULL HOUR in a restaurant, alone is very long. What do you think? I give you the link, you may be more lucky than me.
