NEW YORK (AP) - customers will need to spend more money on the site in order to qualify for free shipping.

The online retailer raised the minimum order size needed for free shipping to $35 from $25. The change, made Monday, comes ahead of the busy holiday shopping season. Inc. is pushing customers to sign up for its Amazon Prime service, which costs $79 a year. Members receive free two-day shipping on millions of items on the site.

In a post on its website, Inc. says that it's the first time it has increased its free shipping minimum in more than a decade.
