I know people that have HIV/AIDS. These people barely have money to live on. They each get four kits per month (on the USA tab, I know) they can use all four, or sell all four. Not legal to sell them, but they take the risk. So a person sells me two kits for 400, and keeps the other two to use. They get 400 more to live on, and I am able to help out the people that I know. I am not greedy, trying to get 400 for a kit, and double my money. I sell it directly to the person who fronted me the 400... and keep 40 for my troubles...
not a big deal really
