Looks like Amazon isn't going to wait a few weeks to drop the price on the Epic 4G: they're already offering it for $200, $50 less than the other big-name stores. The device won't ship until launch (August 31), but they're offering free two-day shipping - albeit, with a minor disclaimer:
The new Samsung Epic from Sprint is now available for pre-order and should begin shipping on August 31, 2010. Due to demand for this device, you may experience a slight shipping delay.
"See price in cart?" Oh Amazon, you're so sneaky.
I suppose that's to be expected with such a major launch, but it's hard not to wonder if Sprint wouldn't be doing a little better right now if they could actually keep up with the demand for their hottest hardware.
