US ecommerce will continue to grow by double digits in 2019 amid a strong economic backdrop that is beginning to moderate compared with prior years.

Grocery is the least penetrated but fastest-growing category in ecommerce today. Traditional brands and retailers need to understand why this channel shift is accelerating and adjust their marketing and selling strategies accordingly.

The online grocery market heats up following the news Amazon is planning to open a new line of grocery stores in locations across the US in 2019.

Last year, 81.4% of global consumers reported ordering items online for in-store pickup (up nearly 30% from the year prior) as more consumers are drawn to the service’s convenience and speed.

2018 was a banner year for US holiday retail sales across both brick-and-mortar and ecommerce. But with more economic uncertainty ahead, the 2019 holiday season is not shaping up to be quite as strong.

Walmart, which overtook Apple last year to become the third-largest US etailer, is widening the gap with Apple. Walmart’s ecommerce sales will grow nearly 33% this year to $27.81 billion.

Walmart is doubling down on its digital grocery efforts with a splashy new campaign promoting Walmart Grocery Pickup, its click-and-collect service.

The numbers aren't in yet, but Walmart might have overtaken Amazon as the largest digital grocery player in the US.

Buy online, pick up in-store is seen as the solution for consumers who don’t want to wait for their package, but according to an OrderDynamics survey, 30.3% of retailers in select countries can confirm an order for pickup—more or less in the same timeframe as standard shipping—in two or more days.
