That's how alot of bloggers make money - endorsing products. In fact there are alot of bloggers being taken advantage of and not being paid decent rates and expected to do all sorts of stuff. Which some of them do without realising cos they are just trying to make some spare cash from home.

and just for the record I'd never flog someone elses stuff on my blog - I think people get jack of it, especially when they will flog anything.....

I'd expect to be paid to review a movie or something, but you would get MY opinion!
