I have two Goodreads Giveaways going now. After they are done, I will no longer be using the Goodreads Giveaway program. The program was great when my investment was the price of the paperback and shipping. Now Goodreads has changed the terms for the authors. The program will cost $120 or $600 depending on which program you choose. People simply don't buy enough books from this program to justify the cost. I will, however, continue to use the Amazon giveaway program.
Cheers.
