Starting sometime in June, shoppers will be able to submit an order on Target.com for same-day delivery - if the order is paced by 1:30pm.
Deliveries will be made between 6pm and 9pm for a $10 fee.
Miami is one of three markets, along with Boston and Minneapolis, where the retailer is testing the service. Target stores in Miami have some of the highest sales in the chain, with the Midtown Miami store near the top in annual sales.
Several other online retailers are testing similar same-day services in other markets such as Amazon, eBay, and Google.
