@JGoldman10,
Those are all pyramid schemes: Herbalife, Primerica, Amway, Avon, etc.
I almost got involved with Primerica when I was young and naive, before I realized I had to pay for my own training. None of my later genuine jobs never forced me to pay during the hiring process.
I never accept out of area calls because they are always marketing scams. Most people, including myself, would usually seek out business opportunities, instead of waiting for them on the phone.
