Lead pays per sign up or filling out a form. Some leads require more action like taking free offers. Sale is when they pay for it and you then get paid. Some pay per lead programs can make some good extra money for your site. Depends on type of program and what they offer. It also depends on what your site is about and is the program something people on your site will like.
I think it's lame when programs try to redefine what a lead is. As far as I'm concerned, a lead is a sign up with complete and valid information. The bar should never be raised on that, it really pisses me off
