Ross does not offer online shopping to keep operating costs as low as possible. Additionally, the way that Ross acquires and manages inventory also makes online shopping uneconomical and unfeasible under its' business model.
The Ross business model is designed to keep costs at an absolute minimum to provide the lowest possible prices on merchandise to customers. This model relies heavily on opportunistic buying strategies at a regional level, thus inventory for individual stores fluctuates constantly and varies widely from region to region. The cost of operating a shopping website with a transient inventory and the necessary employees and other overhead is cost prohibitive under this model.
