Similarly, if the parcel service marks it as "attempted delivery not home" (even though I or someone else was home all day) and drops it of at a pickup on the other side of town (even though they have a branch around the corner) I can just order it again and count on amazon to refund the order (and perhaps demand the delivery service be less shit). For a smaller seller a) more than likely they want me to eat the delivery fee for sending it again and b) even if they cover it they don't have any leverage with the delivery service to be less shit.
