Retail qualifies as a vertical, although I don’t have a retail product to discuss. But here’s a MarketTrack study on shopper preferences for online vs in-store shopping. Despite all the bad news you’ve read about bricks-and-mortar retailers, shoppers in most categories still prefer to buy in a physical store. But younger shoppers lean more towards online and 80% of respondents said they do online price comparisons. So the prospects for conventional in-store retail do look rather bleak.
