the cart doesn't make sense, it's too small and has too specific things in it. cod filet are pricier, shrimps are way cheaper. Great.
The products were picked not to represent an average shopping cart at Walmart (because we already do that and it’s called the CPI), but to specifically target items which they thought would be hardest hit by tariffs.
It’s an entirely unscientific report showing price changes at a single store with an artificial basket of goods with no attempt whatsoever to control for independent variables. In short, it tells us nothing at best, and is misinformation at worst. It’s hard to tell if the effort was even done in good faith.
Then again, TFA’s first sentence is “Shoppers beware.” Maybe that tells us all we need to know. I am actually a bit surprised that first sentence made it to print.
