For the last year I did GfK audits monthly but for the big red store they have and not the blue one. The blue store needs the background checks and the red store is covert.
It was actually not nearly as bad as many people say -- I think the red store is about a 2 hour expected input while the blue store is 4 or 5. Plus I was able to just snap pics of everything then go home and input the prices and other data they needed. After I did it the first two times the scheduler negotiated a good bonus with me and automatically gave me my store monthly. They kept tweaking their reporting software, however and it had a little different learning curve each month. The last month I did it thy changed to a completely new system that was just borked.
All was well and good for a year until she told me 2 months ago that my red store was no longer on the audit list and there wasn't one within a hundred miles of me... so that ended my GfK experience... aside from the monthly audits I have only done an oddball high end appliance shop at a local dealer for them... that paid well and wasn't a bad experience. The phone shops they have out now seem to be similar to the ones I do with the post office company and the one with the grandmas who call you... GfK doesn't seem to have any locally.
That said, they pay like clockwork... and fast!
