I have not done a Walmart merchandising shop for Market Force but I tried their merchandising at Dollar General etc. Horrible! Pay is very low and if they have not had anyone process the inventory for a long time...the place is a mess as far as the "planogram" (how they want the inventory placed) and it takes sometimes several hours to make it right so you can take a photo of what you did...in order to be paid the 1 hr fee that is offered. If you have problems you are to call them, if you are doing the assignment on a saturday or in the evening, you cannot get in touch with anyone.
I have been successfully shopping with approximately 20 companies and Market Force Merchandising fired me! I was not upset. I spent approximately 7 hrs on 2 jobs for $20 total pay. You are better off going to the other side of Market Force, not the merchandising side. There you are paid for what you do, not for the bad job someone else did at that location and you have to correct it!
Just my opinion though. Good Luck.
