I like how easy it was for people who want packages delivered, but don't live at home themselves - parents work all day so when their kids are out of school its not always possible/simple enough just go pick up those things yourself! It makes sure no one forgets about an item from last week because we didn't check our mailboxes every hour throughout the weekend as usual (if there's anything left over after everyone else has taken theirs) then someone will forget something until Monday morning. So much easier than having to remember everything myself :) Also very helpful if your co-workers aren't living near where you do since this can make them wait around longer unless you're able too handle both tasks while still working fulltime ;) Nothing specific really other than being somewhat pricey compared to free services most companies offer these days. We use Parellalerts mostly during lunch breaks which works best for us personally though sometimes i wish employees.
