Malls have decked their halls for holiday shoppers but the majority of Canadians surveyed by FedEx want online deals. Here is how to grab a deal from home: Clear your browser cookies because stores track you and adjust prices. Use flyer apps Reebee and Flipp: they help you search for deals from multiple stores at once. Use Google Chrome extension "Honey" to find coupon codes. Use model numbers to compare apples to apples. Skip extended warrantie.s Sign up for store newsletters to get flash sales and coupons. Ignore hype that encourages overspending.
