I'm new to building a website with Wix and I haven't figured out how to do everything yet, so please pardon things not working the way you (and I) expect them to. For example, I posted a free sample of my book The Templar Lance to the product page, but apparently I can't sell it for $0.00. So, if you would like a sample, send and email to me here at firstname.lastname@example.org and I'll reply back with the sample.
If you have any questions, or want to complain about things not working, send me an email, again to email@example.com. I'll do my best to get everything going properly.
