WASHINGTON — Target is bringing a same-day home delivery service to stores in the Washington area aimed at shoppers who use public transportation, and don’t want to lug what they buy home on the bus or Metro.

Target has been testing the delivery service for in-store shoppers in New York City since last year.

In addition to Washington, Target will roll out the in-store delivery service in Boston, Chicago and San Francisco.

The same-day delivery for in-store shoppers costs a flat $7. Target says shoppers can pick a two-hour delivery window that is convenient for them.

Target says in New York, the Home category, which includes large furniture items, has proved the most popular merchandise to have delivered. It says oversized purchases like furniture might include an additional $25 handling fee.

Target says it would provide the service in 60 stores in its five rollout cities, but didn’t identify which stores they would be.

Target has about 20 stores in the Washington region.

Target, with more than 1,800 stores, has been adding more ways for potential shoppers to get their goods. It already offers free two-day shipping on Target.com and is expanding a drive up service, where Target employees load orders directly into shoppers trunks.

Target will also be making same-day online deliveries through Shipt nationwide by the end of the year.
