So here's the thing... Last week I had you gather all the links to all the places where readers can buy your book(s). Now whenever you write a post on your social media, use a different link every time.
Don't just send your book buyers and potential readers to Amazon - unless that's the only place your book can be purchased.
It's important to give equal time to all outlets. We want all those other places to stay in business, so we need to send business their way at least as much as we send them to Amazon.
