Amazon's widely-known Prime service has been expanded once again as the company unveiled its free-of-charge same-day delivery, exclusively available to customers who paid a $99/year Prime service membership, for a minimum purchased item of at least $35. This new service feature will be open to 14 U.S. Metro areas.

Amazon Prime cutomers must place their orders before noon for their items to delivered on the same day. Amazon has been working for years now regarding the same-day delivery scheme and this is by far their best offer according to analysts as it would potentially throw off their competitors such as Google and eBay.

This free same-day delivery of Amazon will have its customers expecting their products to be delivered at their doorstep by 9 in the evening, any day of the week. The service will be available for more than a million products in their website. These products include books, video games, CDs, coffee makers, and many more. Prime members will have to look for the Prime Free Same-Day logo on the item.

The new service will be called Prime Free Same-Day Delivery and the 14 U.S. metro areas include Atlanta, Baltimore, Boston, Dallas-Fort Worth, Indianapolis, Los Angeles, New York, Philadelphia, Phoenix, San Diego, San Francisco Bay, Seattle, Tampa Bay, and Washington D.C.

If Prime customers will order less than $35, they will still have to pay $5.99 for the same-day delivery fee. As for non-Prime members, they will continue to pay $8.99 for same-day delivery.

This is not the first time that Amazon experimented with their Prime, as in last December, the company launched Prime Now, which delivered 25,000 items to Prime customers within one hour from purchase with a corresponding fee of $7.99.

Greg Greeley, vice president of Amazon Prime said in a statement that it will continue to make its  services faster and continue to look at different alternatives to give customers the maximum flexibility. In line with this, Amazon plans to hire 6,000 more full-time workers and build 50 more distribution centers.
