But when amazon ships for free or even cheap, that's when it really takes losses. So my recommendation would be this:
That's right. Amazon.com, the retailer of tomorrow, the great innovator of e-commerce, the savior of the short story (remember Amazon Shorts?), the promoter of a device so profound we'll have to change the way we conceive cities (remember "Ginger"—the Segway scooter?) also sells sledgehammers and sends them in the friggin' mail. (Or UPS, whatever.)
The Ames True Temper 1199700 16-Pound Double Faced Sledge Hammer with 36-Inch Hickory Handle ships for free with Super Saver Shipping.
A few tens of thousand orders of this hammer, or, even in better, of the premium they have in which this hammer and its sister hammer, a nice twelve pounder, are both available for $90.78, should send a message loud and clear. So don't boycott Amazon, HAMMER AMAZON!
Then, in a few months when Borders goes out of business, we'll all have sufficient hammers to bring down the empty big-box stores before something even more awful takes Borders's place. (Office Depot, ohmigod!)
