You are paying more for COMFORT, specifically a lighter helmet with more venting. If you are happy with a $40 helmet's comfort, then buy it. Otherwise work you way up $10 - $20 and try again.

I would not want to ride 60 miles in the Texas summer in a Walmart helmet, but it might work just fine if you live up north or don't go for long rides.
