Settings are kept per account — where you are, and how your watching runs. Sign in and they'll be here whenever you come back, on any device.
How the watching works
In the background, Slashlist looks up each watched item on Google Shopping — US online stores, and nearby stores once you've set a location — and remembers what it saw. It looks as often as the month's searches allow (None for you right now), and every watch shows when it last looked. The best recent price is what you see on the front page. If you've set a price you'd be glad about, one email says when it's reached; nothing else ever pings you.
