If you do Facebook, you could always send a message to Tradewater Bait Inc. which is Ken's Bait and Tackle in Lake City. I think I saw a rack full of the Shelton's bream bugs when I was in there Saturday.

They also have an online store, but only list a few of the baits they make. There's an email address and phone number there too:
