Free bank wire transfer

I use Paypal to send money to strangers (like on Ebay or Etsy); I use Venmo to pay friends; but if I need to send a lot of money (more than several thousand $$$) I use Zelle. Unlike Venmo which holds a reserve in your account that you replenish, Zelle is basically a bank to bank wire transfer – for free. But the interface is person to person. Still can’t do it internationally, but it is very handy for larger peer-to-peer payments in US. Easy to set up. — KK
