News 6 tested two of the most downloaded apps that promise to help consumers find the best deals, ShopSavvy and BuyVia Scanner. Using the ShopSavvy app on a smartphone, we scanned the product’s bar code, or UPC symbol, and the app scanned prices at other stores online. ShopSavvy's price scanning app showed the price of a Baby Yoda toy at several retailers. “These apps can be really useful,” said Chris Minnick, who teaches app development at the University of Central Florida. News 6 scanned an InstaPot at one local retailer, and the ShopSavvy app showed it was $119.99 at Target.
