Last year during holidays, US online sales surpassed $122 billion. This represented a 12 percent increase over the previous year. But beyond the overall growth, what's more interesting is that sales at physical stores dropped by 10 percent, the result of ongoing consumer comfort with and adoption of e-commerce buying behavior. Given the performance of holidays so far this year, it seems clear that this trend will continue in 2017. As a result, retailers are stocking fewer items in stores to reduce inventory costs and are hiring fewer seasonal workers as they anticipate lower foot traffic to stores.
