The prize on red eyes in Holland isn't high as well,
for juveniles you may pay as little as €7,50-10.

Maybe you have some luck in Manchester.
The first UK frogday will be June 12.
There will be some Dutch people as well,
maybe you can ask them to bring some red eyes with them.
There are a lot being bred at the moment and around that time hundreds need new homes,
so prizes will be at the bottom at that point
