Well, that's where the second thing to look at comes in; how many sales the individual listing has. If more than a half-dozen people have bought it and it's still up, it's costly for the vendor to take the listing down and replace it when a 1-star rating is left. Sometimes you gotta roll the dice, but yeah that is very risky with things like integrated circuits, or really anything more complex than discrete components.
