The most common high-pressure tactic is the lure of getting in on the ground floor. But in direct sales, a good opportunity is a good opportunity no matter when you get in. In fact, you're safer to go with a company that has been around for more than five years (the longer the better) than a start up. Any effort a representative makes to prevent you from studying the company, talking to others, and "sleeping on it" isn't someone you want to work with.
MLM has stretched its sticky fingers out into just about every product market out there, so it’s kinda hard to do something new nowadays. But Jamberry Nails did it. Their adhesive, custom nail designs BLEW UP when they hit the direct sales floor. They built up an army of over 100,000 consultants in the time it takes most people to get a mediocre pay raise at their 9-5.
