I’m a long-time Amazon.com customer, and order almost everything I buy there, largely because of Amazon Prime, where one can pay $79 per year and get free 2-day shipping or next-day shipping for $3.99 per item. Now they’re introducing same-day delivery in certain cities–not mine right now, unfortunately–for $6 per item. I think that’s awesome. I don’t know how many times I’d use it, but it’s certainly nice to know it’ll be available sometime.
