Works great, thank you!
Helpful if you are looking for *any* window. But if there's a delivery slot open that you don't want, it will keep alerting and there doesn't seem to be a way to "mute" for that specific slot so you can make sure to catch any new slots that open up. That, or the ability to select a desired date / time range, would make this a five-star extension.
