My opinion of SR is 180 degrees out of phase with that of Winemaker. My reasoning is:
1- Accessibility-It would literally be impossible for this MSC to be, if needed, more available. Their toll free number is answered by a human, unless, and this is extremely rare, all office folks are busy.
2-Reports-I have completed in excess of 500 shops for SR with nine clients. NONE of the reports have been either excessive or repetitive and all have been inline with the fee.
3-Responsiveness-All workers, including the owner, have always responded to my E-mail queries. I have never had the slightest concern with crickets.
4-Schedulers/editors-Among the best I have encountered in my 15+ years in the business. Each has always been available when I needed assistance.
5-Last, but far from least, bonus money-Folks, this is business; it is not give-a-way land.
I receive extra money, but, only as it should be, when they are desperate.
A final note: The SR pay period is in the middle of MSCs for whom I complete work. I certainly do understand, though, if that is too slow for other shoppers. As for me, I always look at the big picture, as opposed to zooming into a small section and the big ones are 1-5 above.
