Fraud detection service. When someone places an order, an automated text/call is sent to them. Prevents 99% of all fraud. (Can be turned on/off if youre out of balance, but I recently put $20 on it. Most calls cost $.07.
2.) With purchase of this website, will you be able to write up a guide (or if there are already resources available, provide them.) because I personally have no idea on how to run a website.
I will personally teach/tell you everything you need to know.
3.) How much does this website cost to keep running per month? When does the domain expire?
Domain costs are about $10 month with an SSL. SSL is a security label that makes the site more structurally sound. Domain never expires.
4.) How does the live operator system work?
If you look at the site, in the bottom right is the live chat. You can use it with skype or your email. Someone will initiate the chat, you will answer it, and it goes from there.
