The owner was on GPF for a short period of time. They are a well respected wholesaler and sell to a lot of garden and pond stores that sell goldfish and Koi. Also they stock and breed their own fish. If you are just looking for wakins did you look at any of the people on e-bay? Some of them have very good prices. Lewsnews is one seller I would recommend and they have them for $12.99 ea.
I've bought Wakin and other goldfish from these guys: LiveKoiForSale.com Same dealer as Lewsnews on eBay I believe. You can't pick the individual Wakin you want, but I received some decent fish. These are my favorite pond goldfish, and I plan on ordering more from them.
I initial went with the Goldfish Peanuts. Kept them the for a few years. Gave some away here and there when the pond was getting crowded. In 2020 I think, We got rid of them all. We now have Calico Wakins, Black Opal Wakins, Regular Wakins, Black Opal Shubunkins, Sanke Gold Goldfish, and Pretsore rescue.
