But one of the bad side effects of "free" delivery is a race to the bottom in quality. My neighborhood UPS guy is awesome -- he rings the doorbell, if it's raining he puts a bag around each box, if a box is heavy he'll bring it inside for my wife. The local Lasership folks (different ones every time) are far less awesome -- they just drop the box on the porch, not bothering to ring the doorbell, not bothering with weatherproofing. So we've had a couple of boxes soaked, even when my wife was home, because she didn't hear the delivery.
I'd pay a couple bucks more to get UPS over Lasership, but it's not easy for me to select that option with most web merchants.
