I don't mind these $5 fee + $9 or $12 reimbursement at all, except for the hours the shops are confined to. They're on weekends from 12-6, or on weekdays from 4-8. My 2 year old is at preschool M-F til 5, so I can only get 1 done before picking him up. And until recentally, all of the ones in my area where only scheduled for weekends, meaning I had to give up time with him to go do these shops. I'm also not a fan of the fact that the report is due at midnight local time, making it due at best 11.5 hours after completion, but possibly only 4 hours after completion.
But, I coupon and shop for my ill in-laws, so often my regular shopping list involved multiple transactions anyways, so now I just do each transaction at a different store. I do 3-4 of these most weeks, and all but one pay the $12 reimbursement rather than the $9. $36 or more of groceries each week that can be written off as a reimbursed business expense is fine by me! And once I combine that with coupons and rebate apps, I can get quite a lot for $36. As far as the interactions with various departments... Despite my best efforts and visiting some departments multiple times, even before that requirement was added to the guidelines, I've never once been able to accomplish every interaction they request.
Since I try not to spend a lot of time away from home at times that my son is home, I don't usually combine these with any complicated or time consuming shops, but I'll often pick up app jobs in the area, or quick marketforce fast food jobs to add value to the drive.
The reports are simple and go quickly once you get used to them. The only part there that kills me is regarding the interaction with the cashier, which seems to have about 10 different questions asking if they were friendly and paid attention to you. I'm running out of ways to answer basically the same question over and over. The shop it app has been a lifesaver for these shops for taking notes, and I've found that filling out the hard copy from my notes first makes the actual input time go much faster.
