Got milk? Amazon.com does. And the Seattle online retailer is using the staple to lure customers to its Amazon Fresh grocery delivery service in Seattle.

Amazon Fresh has kicked off an email promotion for new customers, providing free milk for one year for those who place orders of $75 or more. The promotion runs through June 3rd.

“With AmazonFresh, you can place an order tonight after the kids are asleep and have your favorite groceries — from bananas and milk to flowers and wine — waiting on your doorstep the next morning,” according to the email explaining the promotion.

Obviously, the marketing pitch here is extremely targeted: Busy moms and dads who might not have time to get to the store each week.  The promotion doesn’t say what size or variety of milk you get, but a gallon of Darigold sells on the site for $3.19. (Organic Valley sells for $6.19).

Amazon Fresh started in Seattle in August 2007, and the company’s lime green delivery trucks have become commonplace on the city streets. It has yet to expand to new cities, but competition may be looming. Walmart just last month started testing a new grocery delivery service in San Jose, California called Walmart to Go.
