My New Spam Folder- Facebook

Has your facebook news-feed turned in to a constant stream of spam?  Are your friends constantly soliciting you to buy stuff from them?  We were discussing this in the office earlier and it seems like a lot of people are having this issue.   What are your friends trying to sell you?  I see a lot of people selling "funny" tshirts.   Have you bought any products that you saw on facebook?  Did they work or was it a scam?
