Food in the US is insanely cheap. Wow.
$4.78 USD at the cheapest store here, and this is on special.
I was about to say that this is roughly what supermarket eggs cost here in Switzerland but then realised that your price was for a dozen and I was thinking a box of six.
Eggs here are often sold in units of one (you fill your own box with however many eggs you need) and cost about US$0.80 per egg.

Food inflation is real but not experienced the same way by many Americans who consume mostly processed foods, which are less vulnerable to commodities shocks. So I can't be too surprised the HN crowd hasn't noticed. But eggs are apparently specially fucked[1] due to an avian flu outbreak, so you're kinda cherry picking. Cherries btw, have seemingly doubled in price, but pre-pandemic was the cheapest they'd ever been in the past 30 years.[2]
More importantly, I think you're missing the point the article and OP were making: dollar store supply chains for these goods suck compared to grocery stores that are optimized for this. Whatever inflation has done to raw goods is amplified at these small dollar stores.
