Thanks for posting that statistic, because I wasn't sure what the US inflation rate is right now.  That doesn't seem to be that high, but compared to all those years when inflation was near zero, it's really damn high.  And yep, that 4-6% doesn't apply across the board for all goods and services. 

Just look at gas prices, which have gone from an average of $2.0x (or something like that) to well over $3/gallon today--and that's a massive hit on people's wallets, since most people drive.  The folks with the huge, gas-guzzling SUVs are taking the biggest hit, though I have little sympathy for them.

Oddly enough, I've noticed that regular Cheetos have been frequently out of stock in my area, though those awful hot ones are still on the shelves.  I've also seen cat food shelves near empty as of late.

As to your question of how bad it's going to get....I have no idea.  I assume the supply chain people are working on a fix and doing the best they can, though that's a pretty generous and optimistic assumption to make.  Let's say I'm hoping those things are true.
