Where is the best place to advertise beauty/weight loss products in Los Angeles?

I'm not from the LA area, but I have a few ideas from when I used to place flyers. One good place is at the supermarket. They usually have a bulletin board there in the vestabule where you can put up flyers for free. I know our local Walmart and Kmart have racks where you can put flyers too. (For bulletin boards, take a little cardboard holder so they'll stand up inside and hang from the bottom of the bulletin board.) There's many other places that have the free bulletin boards in their vestabule too, I just hunted around and found them at all kinds of places. Some restaurants will let you keep flyers on their counter by the check-out (especially if you're a regular customer.) Any place women congregate is good, as well as any kind of waiting area like that. I had one set of flyers at the senior center that did well.
