At least here in Canada, the following was just reported by the government:

DEFLATION:

-Shelter

-Clothing, footwear

-Transportation

INFLATION:

-Food

-Household furnishings/equipment

-Health and personal care

-Recreation, education, reading

-Alcohol and tobacco

So it's not as clear cut (at least here in Canada over the last year) as necessities seeing their prices go up with luxury items seeing them fall.

Rents have gone down significantly here in California since the start of the year. That's a necessity...

For that matter, gas prices were like 50% higher before this crisis began...

Ok, this is the kind of nuanced information I have been craving instead of the yes/no black/white gibberish on the news.
