Where can I buy XBee3 modules now.

Does anyone know where one can buy XBee3 modules at the moment?
I have a few XBee3 modules with PCB antenna (Sparkfun WRL-15126), and I need a few more compatible modules. It seems all suppliers are currently out of stock.

I would suggest contacting Digi Sales at https://www.digi.com/contactus?_gl=1*1qu4urh*_ga*NDQ3OTcxNDIuMTY2NDM2NjA0Nw_ga_RZXDK3PM3BMTY2NDM4OTA4MC41LjEuMTY2NDM4OTMzMy42MC4wLjA.
