Stockholm to Dubai in October under $500. It watches the route and dates you name.

A console, a camera, a laptop, at a named store or anywhere.

A listing site for a type of flat in an area under a price.

If the price is on a web page, it can be watched.
The first message is never the last. Three things people write in the weeks that follow.
The schedule changes; the watch stays.
Answered any time, without waiting for a drop.
One line, and it stops. Watches never count against your daily messages.
Nothing to connect. Name the thing, the limit and, if you like, the store. Checks run in your own environment on the schedule you set and do not count toward the free plan's daily messages.
Every fifteen minutes if you ask, otherwise a few times a day. Checks do not count toward the plan's daily messages.
Say the new number. Stop and it stops.
Anywhere WhatsApp works, on any site with a price on the page.
No. It tells you and gives you the link. Buying stays with you.
As many as you like on Pro; a few at a time on the free plan.
It tells you it could not read the price, instead of going quiet.

One message: the thing, the number, the store if it matters. Then forget about it until the day it drops.
