Release book or wait till other items are done?

Hi,

I've written a how-to book that I'm confident will be very helpful to a good number of people.

I intend to sell the book as a pdf thru a WSO, and I'm thinking about creating a bigger package:

For example, a membership site, with the book available at one level of membership, videos relating to each chapter at another level of membership, and possibly another product at another level of membership.

But before I set up that membership site, I'm thinking of selling just the book on its own thru a WSO.

Then later I'll set up the membership site, or another bigger package centred around the book, and I'll promote that package through another WSO.

One reason for selling just the book first, is to familiarize myself with the WSO system.

But equally, this book, I believe is really good - it will be really helpful for people. It's not a quick hashed-together product. I do want to get mileage out of it. So I only want to follow that process if it's sensible.

So my question is:

Would you say selling just the book to begin with, is a sensible idea?

Or would you say it might make more sense not to sell the book yet - not to create that first WSO for the book - to wait till I have the bigger package ready?

(The book itself is totally ready. The other stuff isn't.)


Thanks
