Great advice! I make it a point to take cash out of the ATM when I go to Costco, because there's no fee. For years, the limit was $400. Earlier this year, the limit dropped to $300, and now it's down to $200. I also try to use a debit card at the grocery store and get cash back. That limit is $50. I was at Target or Walmart a while back, and there was actually a 50-cent charge to get cash back from a debit transaction!
It's not going to get any easier to get cash, only harder, so your recommendation is timely.
