European retailers are expanding their online grocery offerings to provide more convenient options like quicker delivery times and click-and-collect services. Major trends include home delivery from stores or warehouses, collecting pre-ordered goods from grocery stores, and drive-through pickup from dedicated pickup locations. The online grocery market is growing in Europe and the UK, but still only accounts for a small portion of total grocery sales. Leading retailers like Tesco, Asda, Sainsbury's, Waitrose, and Ocado are expanding their online presence through new delivery and pickup options to gain a larger share of this growing market.
