The mystery shopping companies (there are hundreds of them) are weird about folks who “reveal” their clients. I suppose they are justified: why hand out your client list to competitors? But without further ado, I don’t see any harm in telling you what companies I shop on a regular basis.
Fuel (for your car)
I purchase much of my gas at Exxon. Snap a couple pictures of the pump and the restroom, check to see whether the floors are clean, and head down the highway. Through another company I shop Chevron convenience stores, and occasionally some Chevron competitors, I assume for benchmarking purposes. I get so much free gas some weeks that I had to buy a few 5 gallon gas cans to store it all. Those come in handy during dry spells when all the shops have been taken for the month. Another company has a contract with the franchisee of two of the Exxon shops in town. So, I get to shop the same store twice, get paid twice, and get twice as much free stuff.
Fuel (for your body)
Most fast food joints are shopped. I regularly shop McDonald’s, Arby’s, Sonic, Cici's and Zaxby’s. Higher up on the totem pole (and harder to snag), I’ve eaten at Outback, Fleming’s, Ruby Tuesday, and other casual chains.
Fuel (for your finances)
Mystery shopping tends to conjure up images of little old blue-haired ladies wearing bifocals while furiously scribbling notes under their table at Outback. My friends think it’s outright goofy. My friends, however, don’t earn $1,000+ per month in their spare time. Usually each shop reimburses me for a purchase and pays me a small fee. Often toward the end of a month, bonuses are offered. My best weekend of all time: I earned over $800 in two days, plus a free hotel room for the night, 15 gallons of gas, several 2 Liter sodas, granola bars and other inexpensive snacks that satisfied the "in-store purchase" requirement.
