IMHO, PC is a home business that utilizes friends and family for sales and future sales people. I won't say that it is a pyramid scheme
My experience with PC. I have a good friend (I'm her son's Godfather) who's been selling for 10-15 years, so I've received a lot of gifts from PC over the years, along with what my wife buys when she has parties.
1) All stoneware baking dishes (3 pieces) broken
2) Pizza stone broken
3) Metal (large & small) spatula/flippers broken
4) Garlic press broken (boy, did that make a mess)
5) Chopper - I'll be nice and say 'wore out'
6) Peeler - still serviceable and I like it, but I could find the same one at 1/2 the price
Thinking that with the price paid for these items they carried a great warranty, NOPE! Not one could be warranted. So the only PC purchased now is due to the 'required' party purchase. There's equal quality stuff out there for much less, and there's (MUCH) higher quality out there for the same price or less. Again, just my opinion.
If you're asking about the business side of it, it's reasonably good, depending on how you feel about targeting friends and family. You can't be afraid of 'pressing' them to buy something or knowing that they feel obligated to buy something at every party. And if you really work it, your selling them on selling also. Then you'll get a piece of their action along with yours, so press those you know that know a lot of people (with money) that you don't. Good Luck!
