Безопасен ли refundcents.com?

While the site does seem to send MANY* 'links' to coupons, savings, every one of them go through the refundcents site itself... which (nowadays, is understandable, but nonetheless generates a ton of cookies (trackable, findable in FF*... but not in IE*). The last set if coupons, codes received yesterday were 80% expired... which makes me think all they want for me to do is go to/thru their site, preferrably*, on a daily basis. ..probably a good site for most, but I'm sure* generates more phishing emails for me.
