Yes, we were approached about Amway, some deal with putting stripe decals on cars, my wife was talked into trying to sell Avon for awhile. After we left and started attending a mainstream church we were hit up to get into Amway a couple of times, and a telecom deal. My wife's sister (LDS) is always working some scheme or another.
I noticed a funny thing that unites all of these deals: everybody I ever talked to about one was ABOUT to be rich. None of them ever were, but it was going to happen soon. Just like JW's and Armageddon, the big money is always right around the corner.
Once I got into accounting and finance and knew how to read a financial statement I began to be amazed the people running these things aren't in jail. There seems to be some sort of loophole in the laws that lets people get away with this.
