Today I had my first assignment as a mystery shopper. It doesn't pay much, but I know that the company I am doing this for is a valid company. The actual shopping trip was about 20 minutes long, with about 10 minutes traveling time each direction. The required surveys took about 15 minutes to complete once I got home.
The shop only pays $12, but it really isn't that bad for less than one hour's work. I am looking forward to having more opportunities to be a mystery shopper in the future.
