There is no delivery for communities in the easternmost part of the Island, according to a map provided to Newsday by Amazon.

AmazonFresh customers who place orders for more than $50 by 10 a.m. will receive deliveries later that same day. Orders placed after 10 a.m. but by 10 p.m. will be delivered the following day.

The service provides everyday essentials, including milk, apples and shampoo, as well as electronics, which are delivered at a scheduled time. Prepared meals, meat, seafood, baked goods and specialty grocery items are also available.

Through the end of September, all Amazon Prime members in eligible ZIP codes in the metropolitan area, including Long Island, can use AmazonFresh free. Those who are not Amazon Prime members can start a 30-day free trial. After September customers will need a Prime Fresh membership, which is expected to cost $299 a year.
