If you're the sort who just can't wait to get household goods but cringe at having to brave the lines at the local store, today might be your lucky day. Amazon has officially expanded its same-day delivery options in six cities that include Baltimore, Dallas, Indianapolis, New York City, Philadelphia and Washington, DC. You can now order from a catalog of a million common items (such as movies, games and supplies) and expect to get the shipment within hours. You can pull the trigger as late as 12:15PM in most places, and up to 1PM in Baltimore and Washington. Just be prepared to pay for those urgent arrivals. As before, same-day shipping costs $10 (plus 99 cents for every extra item) if you're an ordinary customer, and $6 for all items if you're a Prime subscriber.
