Product registration Special E-mail offer: $20 in savings on future Philips Norelco purchases

The offer does not state any particular product or even a product class.

However when I receive the supposed savings in an e=mail I was required to purchase a specific product for a specific amount of money. I would not be so dumb but usually trust before I get burned. They have my personal information now and I am out the 20 dollars. Live and learn. Philips Norelco offered no recourse other than writing a letter to their office. I gave them one better and filed complaints on several online sites.
