I would assume they are not sold in stores havent looked though. I see alot of pentecostal folks online saleing them so I would go for the pyramid thing
But the question othere then how you get them is do they work? I wouldnt want to get rich off of them just get thinner...
I know how to loose weight but dont seem to be able to make myself stop and eat thus I stay the same size I am. I walk about 4-5 miles a day give or take a few days and dont loose any weight. So I'm game I'll try anything once

Just thought I would get an opinion or two from folks not trying to sale me something
