I hoped that they'd solve a superset of this problem where you want a set of items from one of more sellers. This arises because some sellers split items and each item gets different but overlapping auction period. You'd prefer to buy two or more complementary items from the same seller because they match and because combined shipping may be cheaper. However, if a vastly cheaper complementary item finishes in the meantime then you'd be a fool not to bid.
