Carbord Ltd (C) is a building materials wholesaler. On Monday morning C received a letter containing an order from a regular customer, Home Interiors Ltd (HI), ordering a certain number of gyprock sheets, with measurements, to be delivered to an address in Sydney the following Monday. C immediately posted its confirmation that the order was accepted. This letter would have ordinarily taken 2 days to reach HI's place of business but, due to a strike affecting Australia Post, the letter was not delivered until Friday afternoon. On Friday morning, having not heard from C, HI, believing C were not able to supply the materials, ordered the same materials from an alternative wholesaler. HI sent a fax on Friday afternoon, before the mail was delivered, to C cancelling the order.

HI is now refusing to accept the gyprock sheets from C, or pay for them. Advise Carbord Ltd.

How would your answer change if the order had been received by email on Monday morning and the return email confirming said order was slow to reach HI due to a hacking incident to HI's server? The confirmation email entered HI's server on Tuesday morning, but HI had faxed a cancellation of the order at 4:15 pm the previous day, Monday.
