I haven't used a beta reader but I have been one. I didn't receive (or expect) compensation. After all, I got a free copy of the book and got to read it and blog about it before the general public did.
Marcy. Thanks for stopping by. I've wanted to use beta readers, but I wasn't sure who to ask or if I needed to compensate them. And then if I did, I wasn't sure if I should give them cash or a gift card.
