I'm in Denver as well, you can't find regular eggs in stock. The only thing I can find is the cage-free/brown egg stuff. So this price isn't too far off (especially for King Soopers (Kroger). I've seen price tags for as low as $5.50, but never in stock (this was at Trader Joe's).

I go to a local grocery store, end of last year a dozen eggs could be had on special (pretty regularly) for $1. I spent $4.50 for a half-dozen on sale... ($9/dozen). It came with a card that said Jubilant Julie is the bird of the month, LMAO. This was the cheapest option, including sold-out stuff.

My recommendation to OP is stop shopping at King Soopers and Safeway. Shop around, try out Sprouts, Trader Joe's, Target, etc. Or, better yet, find a local grocery store (Brother's Market, Max Market, Clark's Market, Sun Market, Syracuse Market to name a few). Not only will it probably be a better product for the same/less price, but you'll support a local business and you won't have to wait in line for 10+ soul-crushing minutes.
