To stay competitive, many retailers (e.g. Amazon, Costco, Sears…) offer a 30 day price protection guarantee. It means that if they lower their price within 30 days of when you purchased it, they’ll refund you the difference. But, the majority among us still do not remember to the check price again, you?
PriceProtectr is a new website that watches for prices to drop and if the store offers a money back guarantee, it will notify you if you have a price difference coming your way.
People’ve already saved 2320$ with this service. But, I believe, the real message for marketers is price transparency is automatizing.
