An article in Bloombergbusinessweek (April 2, 2012) cites WalMart’s 8 % growth in 2011 vs Amazon.com’s 41 % growth as reason for WalMart to innovate in the ecommerce space. The result (a) Endless Aisle – which permits customers to order online any items not in the store, (b) Pay With Cash – for customers without credit cards to order online and pick up at the store with cash, (c) Shopycat – which scans a customer’s Facebook friends preferences and suggests gifts. Will these festures be sufficient to combat “scan and scram” – whereby customers scan items in the store and purchase from cheaper e-tailers ? Given Amazon.com’s lead, will WalMart be able to use its $ 264 billion US sales heft and physical store presence to compensate ? Will upcoming ecommerce transaction sales tax collection requirement level the playing field between WalMart and Amazon ?
