pyramid scheme?

I was eating dinner at the student center waiting on my date when a guy sat next to me and said he had a great opportunity for me. He told me he was with Theta Chi and if I bought 30 bottles of his shampoo and managed to sell them all I could get a bid. He said If I brought more guys to rush, then they could sell shampoo also and not only would we all get bids then, but I'd be able to miss some of the harder days of pledgeship. As I became a brother I could move up the ladder and recruit more guys while also making good money on the side from all the shampoo they sell. The fraternity would not only be giving me valuable life experience in managing others and running a business, but I would be working next to my brothers.

Is this guy legit? is joining a fraternity like Theta Chi really as easy as selling a few bottles of shampoo? I Did't realize greek life worked like this.
