I don't know if they are legit, but once you click, they are rapid-fire persistent, which to me was questionable. Their interaction is similar to scammers I have experienced on FB. Once you agree to pay them, they hit you with a chain of additional offers. Then their site tells you to call to confirm, while you also get a text and an email, but no tangible receipt to prove you've bought something. I got spooked when my CC company texted about a questionable charge. Booksi ultimately refunded my money, but not until I had already canceled the credit card. Aarrgghh. It was just not worth it. If you provide a good product or service, provide it. Don't play the same game scammers play.
