Can authors add discount coupons in the book descriptions? Or do you have plans for giveaways?

No, the book description is only for what the book is about.

I am looking at coupon and giveaway options as we get further along. 

If you have ideas on how that might work, please email forauthors@shepherd.com, as I would love to hear your ideas. 

P.S. Would you like to help us build features like this faster?

I launched a membership program for founding members at the urging of authors and readers. 100% of the money goes toward developing new features and my goal of hiring a full-time developer in 2023 (currently, we only have one part-time developer).
