Sending My Customers Locally

If and when I get this book finished (nowhere near) and assuming I put it on Amazon in different locations – USA, UK, etc. – then when I write about it and want to direct potential purchasers to the right country depending on where they are visiting from – how do I send them to the right place?

Use Geniuslink, which for $5/month does that

Geniuslink detects a reader’s country, language, device, and more, then routes them to the best store for them. It’s automatic for Amazon and iBooks. Plus, you can define custom destinations for any other online bookstore or site. Guaranteed safe for Amazon and iBooks.
