I just came across this COVID Economic Impact Report that was put out by YELP that says CSA sales are up 579%! I'm not exactly sure how/where this data was collected, but thought it was interesting to see one source confirming what many of us already knew, that CSAs sales are up!
It's not actually sales,
"Our measure of interest is consumer interest, measured in terms of daily U.S. counts of a few of the many actions people take to connect with businesses on Yelp: viewing business pages or posting photos or reviews."
...but this surely translates to a bigger market share of CSAs, I'd think!
