I actually bought their 2-year supply back when they were doing that. Details here. I guess it's the best $30 I've ever spent since I'm still using the same blades. Change every couple of weeks depending on how ratty they get (so it's more than a two-year supply) but I've never had any noticeable irritation. I do prefer the occasional Gillette as well as "pass-thru" cleanability as mine can get kindof gummed up and difficult to rinse otherwise.
