I've been using the CCs exclusively since the lockdown, even for charges less than 5$ now.
Although I sanitize my hands when I get home, actual currency and coinage is more suspect, due to all the handling they accrue in one day alone.
I must admit when the lockdowns were starting to be suggested, I was half-contemplating withdrawing 500-$1,000 from the ATM in 20s, 10s and 5s, and then getting a bunch of 1s and then stashing them in my truck just in case other people people panicked and started doing the same, and then the banks started folding, as some discussion forums suggested was going to happen!
Glad neither of the above happened.
I withdrew $100 from the ATM around the beginning of March and still have $80 left, whereas before, I used to keep and replenish the $200 in my wallet at all times.
Now though, I do want to go the the bank and get forty of it in brand-new five dollar bills, and maybe ten dollars worth of it in brand-new singles, both for usage on the rare occasion I go to the Dollar Store, as I will use my CC every other place.
