You can great deals on ebay for helmets...I have bought two there; saved considerable amounts of money and they were both great.
XJguy - couple things in response. I think most helmets that are sold in ski shops come with the ASTM and/or the CE certifications. I would agree with your recommendation to only buy a helmet with the certifications, but I don't think I've ever seen any that don't have it. Maybe at Wal-Mart you might find somehting like that. I think if you stick with established ski/board helmet brands (Leedom, Giro, Pro-Tec, Marker, Briko - I know I'm missing some) you should be OK.
The thing I don't quite agree with is the suggestion to buy the helmet on eBay - or at least I would qualify it. I would only buy a helmet on eBay if I could try it on to insure a good fit, and if I could verify it was new. Like with ski boots, fit is the most important thing when it comes to helmets. You can't always tell if a used helmet has been in a crash that would have required it to be replaced.
I have a Giro 9.9 and love it. When helmets started getting more popular, I was worried about being too hot, but it's not an issue with the 9.9. As some have said, the most frequent use is protection from the over anxious safety bar puller.
