For these shops, I just carry my smartphone and do the survey throughout the store as I go. Everyone plays with their phone in the grocery (especially this one -- in my area, they even provide free wifi!). I fill in the Geoverify and the time entered, go to the department portion and then go to another aisle and fill in the info while it is fresh in my mind. Pick up a small item or two for the reimbursement then head to the cashier. Fill in that info and the exit time when you get to the car. Don't forget to save as you go as well as it will timeout if you don't.
After I get done with the first department, it's repeat for the second department. You do need to have distinct and different exit times for each department. Also, be sure to go through a different cashier each time.
Last time I did these (last weekend), I had three departments with $7 bonus on each one!
Shopping across Indiana but mostly around Indianapolis.
