A large body of academic research has recently focused on omnichannel retailing especially on brick-and-mortar (offline) retailers adding and integrating online capabilities . Relatedly, trade press has highlighted how offline retailers have been investing heavily in the use of their existing physical retail network for quicker delivery and pick-up of online orders . Looking at the competition between Amazon and Walmart, however, we demonstrate that focusing on quicker delivery is not the best strategy for offline retailers when opening online channels to compete with online retailers . We estimate a multivariate probit model using data from a customer survey and find that offline retailers should instead focus on delivering the fundamentals of retailing to their online customers too – larger assortment, competitive prices, and purchase convenience . Further, we employ cluster analysis to show which demographics are good targets for retailers as they develop omnichannel capabilities, as well as which demographics retailers need to keep loyal to their original channels.
