Many people enjoy the convenience of Amazon Prime, which for $79 a year gives you free 2-day shipping with no minimum purchase requirement, a decent streaming-video library, and a so-so Kindle book lending library. You may also know that you can share your shipping benefits with other people in your same household (with the ability to use multiple shipping addresses). At the same time, many people choose to get their stuff shipped to their workplace as one of those addresses. Amazon now explicitly allows you to share your shipping benefits with four other coworkers, which mean 5 coworkers can get free 2nd-day shipping by splitting $79 a year. See Share Your Amazon Prime Benefits:
Free or paid Amazon Prime members can share their shipping benefits with up to four additional family members living in the same household, or up to four coworkers. Other Amazon Prime membership benefits such as Prime Instant Video and the Kindle Owners’ Lending Library can’t be shared.
[...] Amazon Mom and Amazon Student members with Amazon Prime shipping benefits and customers receiving a free 30 days of Amazon Prime benefits with Kindle Fire won’t be able to share their benefits.
Only the primary owner gets the video streaming, but I think the shipping benefits are worth the most as Netflix only runs $7.99 a month with a bigger library. The only slightly hard part would perhaps be to collect payment, but really a free lunch per year should do it. Go make some friends!
