My issue is usually amazon sending the wrong item, or counterfits, dispite their occasionall asinine packaging of my items. That is, assuming the seller bothers to correctly list the item. But they seem to be doing little about any of it.

For instance, I recieved 2 vacuum tubes last night. (I ordered 4), and they came jammed in a huge box with no padding on 2 sides. Already scheduled for return. My return rate must be 1 in 10 these days.

Is their warehouse overhead so low as to cover this long term? I honestly don't know. But I also know I would stop doing biz wih them in a heartbeat if returning things was difficult. I did so with ebay/paypal nearly a decade ago and am happier for it.
