Record usage of grocery delivery services amid the COVID-19 pandemic has led to delayed orders, fewer open delivery windows, and an inability to even book a delivery time slot, on occasion. Walmart now hopes to capitalize on the increased demand for speedier delivery with the introduction of a new service that allows consumers to pay to get to the front of the line. The retailer confirmed today it’s launching a new Walmart Grocery service called “Express” which promises orders in 2 hours or less for an upcharge of $10 on top of the usual delivery fee.

The service has been in pilot testing across 100 Walmart stores in the U.S. since mid-April.
