Actually had a brief experience with the Concierge Service:
I was driving to San Antonio for my fiance's birthday and I wanted to stop and get a present at a James Avery jewelers (they are a tx based jeweler that sells silver jewelry), but I wanted to stop at one that was either on the way or close to where she lived (as there are several stores scattered throughout texas). So I called the ML Concierge service on my cell phone while driving. I got a guy that was very helpful and he looked up the website and told me all the locations in San Antonio. When I heard one that was on the way to where I was going, he even offered to connect me directly to the store (kinda like a 411 service). The whole process probably took about less than 3 minutes. I was pleased with their competent and friendly service!
