If you have a smartphone, this holiday shopping season Scanbuy should be one of your powerful weapons. It alows you to download its ScanLife mobile barcode scanning application on a smartphone that could obtain information about products (price, coupon, etc.).
What's the most scanned product category? You guessed, toys!
Of those products scanned by shoppers, what's the most purchased category? Books!
Of course, I would suggest you still check the giant online bookseller Amazon before you buy anything offline. Amazon has a free reading app that you can download and then you can read everywhere on any device. Check it out!
