Coupns and site PR/value

Can making online coupoins available on a site weaken the PR/value?

Is it a ‘red flag’.

The site I’m referring to offers consumer information/reviews, and I’m thinking about keeping the coupon page as seperate as possible (no juice to them, but from coupons stuff t –> quality content)

Same question for weight loss programs.

I do not think so it will affect the PR value of your website.

Coupons or whatever does not affect PR or SEO, unless you are talking
about some sort of dhtml javascript popup that is blocking your site.
