Buyers often accept three major trade-offs: owning something before they possess it, taking responsibility before they control it, and adopting a legal position before gaining operational control. These aren't minor considerations, even when they make sense.
They may allow the buyer to compete without having to just simply raise the price, but the cost is different. The buyer is accepting ownership before possession, responsibility before control, legal position before operational control. This trade-off can and usually does make sense, but it should never be treated as a minor trade-off.
