Today, Amazon.com

unveiled a new subscription service called Amazon Prime, which, for the bargain price of $79/year (at least initially), will enable the subscriber to get unlimited two-day shipping on any order. Considering that they charge about $10 per book for two-day shipping, you'd have to buy 8 books per year (or 5 DVDs, for which they charge $17 for two-day shipping) in order to make it worth it. For a rabid internet shopper like me, it'd probably be well worth it. Of course, they'll probably raise the price sooner or later.
