Do smartphone apps really find you the best deal while holiday shopping? News 6 tests 2 of most downloaded price-comparison apps Updated: Tags: ORLANDO, Fla. – For many people struggling with finances during the COVID-19 pandemic, finding a deal this holiday season may be more important than ever before. News 6 tested two of the most downloaded apps that promise to help consumers find the best deals, ShopSavvy and BuyVia Scanner. Our shopping trip began with one of the most sought-after toys this holiday season -- Baby Yoda. It retailed for $17.99 at Target, but was that the best deal? 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.
