Reptile Care and COVID-19

I’m a bearded dragon owner in the Seattle area, and a lot is happening right now with coronavirus. I’m worried about pet stores and grocery stores being forced to close.

Do you guys have any tips for stocking up on reptile food? I feed my beardie fresh greens and live crickets and superworms (my dubia colony stopped producing). What can I buy now that will last a long time? Are frozen greens acceptable?
