As someone who grew up in the Denver area, here is some additional context. King Soopers is the grocery store that most people go to(Kroger owned). The Kroger brand eggs are the cheapest they offer and in the city they are $7.89 a dozen. In the suburbs $7.39. Downtown supermarkets are always a little more expensive. There are some egg brands priced at $10.99 and higher but the cheapest ones are still getting really expensive. And that's if they aren't sold out due to the shortage.
In Colorado Springs, I'm seeing Eggland's Best at $6.29 and Simple Truth "Kipster Large" eggs currently on sale at $4.99 per dozen, respectively, at King Soopers.
While these prices are certainly high compared to what we're used to, it's definitely not been nearly as outrageous as what I'm seeing online.
I can't imagine the prices and selection are actually significantly different at the same chain an hour away in Denver.
I'll clarify. Not all the prices in Denver are going to be that high since Denver is large. My example from Speer Blvd was likely a worse case scenario since it's downtown Denver. Not on the edge of the city limits like 9 mile.
You said you can't imagine the prices being that different in Denver. In some parts, it is. The deals you posted at 9 mile are not representative of Denver as whole. Likewise with the more expensive downtown locations.
So your point is just that convenience costs more? I don't think that's really any kind of news flash for most people.
Whatever dude.... I'm not going to waste any more of my time to prove it but I'd bet that the exact same options are actually available at the location you shared screenshots from, as well.
