Seems a bit illegal. Also do not run random scripts from the internet which control your browser. For all we know, they could be scraping your own sensitive data.
This is a clever hack. However, I'm guessing that if the coupon sites you're scraping notice a lot of scraping activity, they'll start hiding the coupons behind CAPTCHAs to block the scrapers.
