An offer to sell does not ordinarily become a completed sale without the legally required acceptance. Therefore the time at which a consequence introduced by faa takes effect may turn on acceptance and completion of the contract.
Separate three questions:
1. Has an offer been made?
2. Has a legally effective acceptance occurred?
3. If so, when does the stated consequence attach?
Keeping these questions separate prevents the linguistic sequence introduced by faa from being confused with the substantive requirements of a valid sale.
