At the beginning of July in1997, the price of ordered goods was marked down sharply on international market, then Company A informed Company B saying: “we cancel the price of the previous order, if you are willing to reduce the price by 20% then the duration of offer will extend until 20July”. After receiving the notice, company Bwrote back promptly on July 3rd and disagreed to price cutting, and accepted the previous offer. Normally, the letter could reach Company Aby July 8th, but Company A was only able to receive it on July 15th due to the labor strike in the post office and Company A replied immediately, saying: “the first order is already revoked, your acceptance is void”. Company B insisted that the first offer was irrevocable. Company A sent another reply claiming that Company B`s acceptance was delayed and therefore the contract does not exist.
