re: Anyone ever set up a Group Buy?

I’ve done it for car parts, I started by approaching the vendor to ask if they were open to them, number of people required, if they would only ship to one person or each person in the group and what the estimated cost would be. In my case I knew it was a highly desirable item that wasn’t available retail. You might want to start with a group buy feeler and assume 1/3 of respondants won’t come through and approach with that number. Don’t be surprised if they have a dealer network if they won’t even talk to you
