Sadly, we still do. But it’s really more a matter of vendor preference these days, since some places (usually small/personal operations) don’t do digital payments. That and nobody carries large amounts of cash around, so checks are the only alternative.

That said, anyone that hasn’t moved on to prefer a bank card or credit-card is behind the times, or doesn’t have a bank account. Still, it’s rare to see these days, especially at the grocery store.
