A friend of a friend emailed me and asked me out for a date. He's a nice guy, but I don't want to date him. What's the proper way to say this? Be blunt? Don't reply to the email?

Last night I planed the back deck some more and went hot tub shopping on line. I can buy a good hot tub from Home Depot or Costco for about $3,000.00 less than Jacuzi or Olympic. Jacuzi may have some special features, but it won't make me $3,000 happier than the Home Depot special.
