Online coupons: print, buy, and swap

I read in a news story weeks ago that people get 90% of their coupons from the newspaper, which is crazy because there are SO MANY COUPONS ONLINE. If it sounds like I'm shouting it's because I am.

If you only clip the Sunday newspaper, or are holding back because you don't get a paper or don't own scissors, you are missing out! And I don't want you to miss out.

There are three main ways to get coupons online. With the way newspapers are struggling, I wonder if Web sites will soon be the preeminent place to get coupons. You can print them from coupon sites, buy them, or trade for them.
