wilbooks - someone knows it?

someone has ordered on this site?

I ordered free samples before. They are nice, but the samples I got were way too below my son’s reading level. I guess they were pre-k. They just had a single word and picture on each page. Those would be great for a child just starting to read. I have not seen any of the other books, but I’m sure they are pretty good quality. The pictures were nice and clear.

I’m not sure if you can still order free samples?
