E-tailing used to refer to shopping sites such as Amazon, Zappos or Walmart.com. A whole new class of web sites and mobile applications has emerged that let customers find promotions or search for pricing across local merchants. Most are similar to Groupon, which features a daily deal in major markets (often a 2-for-1 spa offer…). Recently, there has been a flurry of small transactions in this space. Groupon, Tippr and others are currently rolling up regional competitors. More interesting are product-specific applications like Red Laser (acquired by eBay, click here for our eBay/RedLaser M&A Alert) and ShopSavvy, which use barcode scanning to find better deals online and locally.
