I'm pretty sure Amazon runs a tight ship, but isn't the real issue just trust? I know i can trust Amazon to deliver the goods and a few other large Amazon-like sites I can also trust but I have had trouble with some smaller etailers so i only use those if i have to. Just this week I had a lunchbox not get shipped because they were out of stock. Not just that (I should not have been able to buy it if they werent able to deliver) but I actually had to email them before they noticed it and paid back the money.
