I started selling used books in December. So far, everything is going fine with a modest but steady stream of sales and no issues with the merchandise. My account is listed as Healthy. But, I am still not getting the Featured Offer after four months -- even when mine is the only Prime copy and the price is the lowest.

So far, my store has no reviews. This makes sense to me because I am selling used books. Do I need to do something in particular in order to encourage buyers to leave a review? I've read that having a minimum number of reviews is necessary in order to be considered for the Featured Offer.

I'm wondering if it makes sense to continue paying the $39.99 monthly subscription fee, or if the Featured Offer status will ever kick in to help me move my stock.
