I can't remember the last time I did a mystery shop. At first it wasn't a conscious decision. Mystery shops aren't as convenient from the new house. The closest ones I've seen are more than 8 miles away. The new job has (somewhat) set hours. It also keeps me in 2-3 set locations, not running all over town.
All of those factors, along with general new house crazy, caused a severe cutoff in mystery shopping last fall. When I laid out which tax documents we should be looking for I officially decided to cut mystery shopping. Outside of babysitting I decided that if I don't get a 1099 or a W-2 I don't want to deal with it.
Well doing our taxes has been a pain. I fall into the claim all income camp, not the claim my main job but side jobs don't count. By nature I'm a worrier and I'd rather not have to deal with the IRS over something stupid. Last year between the two of us it was something like 3 W-2's, 3 1099's, and 2 self maintained records that were additional Schedule C's. The amount I was making mystery shopping, when balanced with the record keeping and extra rigmarole at the end of the year didn't add up.
Currently I don't have as many earning opportunities. On the flip side I make more per hour with my current opportunities, largely babysitting and working at the museum. The money is almost equaling out and I have time to do the thing I enjoy.
