stevejsmith writes "Amazon.com has announced their Amazon Prime service. For $79, you get free two-day shipping on all items, upgradeable to overnight shipping for $3.99 per item. The offer applies to most media (books, DVDs, CDs, etc.) and can be shared among "up to four family members living in the same household." Apparently the only way they will enforce this family-only sharing clause is by mandating that your "family members" know your birthday."
