Blackwater's Aquatic Nutrition has its own booth. And, Koi Acres will have Tomigai for sale. And, Ultra Balance has its own booth. And, I believe Kodama will have food for sale. Genki Koi and SoBe Koi have indicated they will have dry goods as well as koi for sale, but I'm not certain they will have food. And, Hikari has a booth, but does not sell... except bags used in its display may be made available on Sunday instead of paying to ship them back. Hikari does not want to sell directly, since that puts them in competition with their dealers.
I was not able to entice Kenzen, Mizuho or FD dealers to get a booth. Maybe next year they will grow to appreciate how being at the major shows can grow their customer base. They purchase repeated ads to reach 2,000 readers of a koi magazine, and could reach that many in person by being at one major show. I think an in-person contact is more effective than an ad folks flip past. I know a lot of Tomigai was sold last year at the show, and it gained a lot of converts who now use it regularly.
