It depends alot on where you live. I'm in OC Calif. We have shoppers coming out of our ears, and I believe that my gold cert. has given me a leg up at times. (Especially if I'm requesting a shop from a MSP I don't have a track record with.)
OTOH, you may not find it necessary at all if there's not much competition for shops in your area.
I do know that some MSPs (not sure how many) send out email shop notifications to gold shoppers first.
