I had a coworker and friend who is a PartyLite consultant and she loved it. She even made quite a bit of money doing it.
Part of her success had to do with her personality, she was super sociable and bubbly and so she had several parties a week most of the time (a few crazy weeks she had 4 parties!). She also has a lot of friends who are consultants for other products (pampered chef, body shop etc.) and they would trade off hosting for each other which worked really well.
I also knew people who tried it and couldn't make it work. It really depends on your social networks, your personality and the time you have to devote to it. My friend spent a lot of time on her PartyLite business, she put a lot of work into it. I think that was the other main difference between those who made it and those who didn't. She would call her hosts, sometimes call guests to make sure people were showing, she would do extra promotions, she put a lot of time into it.
And she loved the discounts! Her home is decorated with all kinds of beautiful candles and candle doodad stuff. She would also donate candles to different fundraising events (we worked for a nonprofit) and promote her business that way.
I love PartyLite candles! I think they have great stuff but they are sometimes pricey so I was never a top customer LOL.
Good luck! Hope this testimonial helps you!
