Rose, that's a bummer. Here's a couple links about sites like that:

You'll probably receive a letter saying your poem has been picked and will be published IF you agree to buy the book AND send them $50+ dollars - a lot of money for a book!

I know a woman who's in one of the books with several poems. She even paid to go to the ceremony to pick up the book. All she wanted to be was published. She's happy.
