A promise to keep an offer open is not binding
unless the offeror has provided consideration. Routledge v Grant (1828) Grant wrote to Routledge offering to
purchase the lease of his house. The offer was to remain open for six weeks.
Grant then changed his mind about purchasing the lease and, within the six
weeks, withdrew his offer. After Routledge had received Grant's letter
withdrawing the offer he wrote to Grant, within the six weeks, accepting
Grant's offer. Q Could Grant withdraw his offer
within the six week period?
No,,, there's no contract between them
