WASHINGTON (Reuters) – Walmart Inc is stepping up its battle with Amazon.com Inc by offering one-day delivery without a shipping fee, weeks after Amazon announced a similar offer – a move that will intensify the race to deliver orders to shoppers faster.

On April 25, Amazon said it plans to deliver packages to members of its loyalty club Prime in just one day and expects to spend $800 million toward the shipping goal in the second quarter alone.

Walmart’s offer applies to fewer products. As many as 220,000 items, which are the most frequently purchased, ranging from laundry detergent to toys and electronics will qualify
