Where can someone buy ifa book in Yoruba language?

I don't think you can get explicit information from any book. In this generation, Ifa secrets is only open to initiates.

To know the context of Ifa you need to be a Babalawo, not by reading books or online articles.

The verses of Ifa are called Odu-Ifa and they all carry a story with hold several interpretations which only a Babalawo can decipher

Go to Unilag bookshop, you will get Yemi Elebuibon's latest work on Ifa still selling fast on the shelf, or better still Wande Abimbola's works. These are two published great Ifa veterans. Goodluck.
