A short time ago and maybe still, container ships were sitting in the ocean full of cargo that was purchased pre-super inflation. Places such as Home Depot are filled with inventory and some are even building storage areas because they have two choices, sit outside or pile the aisles. That's because they're getting all that delayed stock.
That seems to mean their cost for many items never increased relative to their current price increases.
IF that's true then they are simply raising prices and blaming inflation, inflation in part they are causing. Are those black Friday sales simply pre-inflation prices with the same profit margins?
