Amazon has Logitech's HD Pro Webcam C920 on sale right now for just $45.99. This is typically priced around $60, and has an original price of nearly $99. So this is a great price for a great webcam, it'll be great for video calls, and even some streaming.
The C920 from Logitech is perhaps the best webcam you can buy, without paying a ton for its new 4K webcam that it debuted earlier this year. The C920 is a widescreen webcam, so you'll get a lot of area in your shot, and it shoots in 1080p with a Carl Zeiss lens on top. That Carl Zeiss glass is going to be great for getting a really crisp image. In fact, most people won't even know that it is a webcam, and might mistake it for a regular camera, because it's just that good. There is also a tripod mount included, so you could mount it on a tripod, as opposed to putting it on top of your monitor.
