Waiting for a price drop: it kept watching, then flagged $93 off unprompted

What it does
Two weeks after being asked for the best desk walking pad, Muse came back on its own to say the pick was $93 off, with the sale ending the next day. Nobody told it to monitor the price.
Why it is worth it
The right moment to buy is easy to miss. An agent that remembers what you wanted and keeps an eye on it does the waiting for you.
