Why are you people hoarding food?
At lest where I live there is no shortage of anything except hand sanitizer and masks, ..
Still hard to get headphones or webcams here, unless you want to pay over 1K for a USB webcam.
I thought "that can't be right", but then I checked what the major electronics shops had in their stores here in southern Sweden, and they were all out.
But after some googling I found some ranging from 30-500 USD equivalent, both in swedish online shops and on Amazon and Aliexpress.
But I have no idea where you live, so that might not be a good option for you.
