As of 2015, Amazon Prime costs $99 annually, and there are no additional costs associated with maintaining the membership. However, members may have to pay extra for expedited shipping or media downloads that are not covered by Prime benefits.
Amazon Prime memberships are billed on a yearly basis. While the membership is active, members have unlimited streaming access to Prime Instant Video and Prime Music. Kindle owners can borrow ebooks for free through Amazon Prime's Kindle Owners' Lending Library. However, not all movies, ebooks, albums and media are included in these services, so users may have to pay for specific items.
Amazon Prime members receive free two-day shipping on most items. Expedited shipping is available for an additional fee. Two-day shipping is not available for certain items, and members must pay for an alternate shipping method in these cases.
