Been a rep for over 2 years now. I haven't really had any problems but I try to stick to selling to people I know. I just like being able to order myself demos.
Anyways, if you get an online order saying "I want to order products." It IS a scam. If they refuse to pay for their order online or refuse to meet you in person, it is a scam. I have never ever had a contact me request that wasn't an attempted scam. Scams are easy to spot and no one should fall for them.
As for making any money goes, I don't. I just like being able to purchase demos. I save a lot of money on stuff like makeup, shampoo, and lotions. I also purchase a lot of gifts through the demos.
