BuyVia, the first website and mobile app that combines in-store and online shopping across smartphones, tablets and laptops, has released a new Personal Shopping App for the iPhone, Personal Shopper 4.0. Users who are seeking a bargain will be able to enter what type of product they are seeking and how much they are willing to pay. Once saved, the user will receive an email when either the BuyVia Shopping Expert Team or a fellow user finds a deal that meets the criteria.
