Heh, I got the same free blade thing from being a costco executive member. I've never used an electric shaver. It almost seems like cheating. But it comes down to whether you want to pay up front for an electric (which still uses electricity and needs maintenance), or just go with disposables. I wouldn't be surprised if the costs are similar. Personally, I'm not crazy of the idea of having a motor-operated razor shaving my face, I'd rather just use it myself. It isn't that hard. Either that, or Rambo it and use a hunting knife.
