I also drip feed items to my doorstep instead of doing one huge order with many items in it, that way I compartmentalize the order so that if a small order doesn't arrive, I can live with it. This should be common sense, but some people are so impatient that they have to have everything in one big order rather than span the items out over time.
Also if I want some expensive gadget like a laptop / iPad or whatever, I go to my local brick and mortar store for that. Buying high-spec luxury goods on Amazon is a bad idea.
