Currently doing my coursework question which is due in 4 days and worth 40% of my module grade and I have no idea where to start.
The basis of the problem if person A advertises something on gumtree, person B makes an offer and it's rejected via post. Later in the day person A accepts it via post, but person B emails before receiving the letter increasing their offer. Person A then accepts the higher offer. I must advise person B
If anyone even could suggest relevant cases that would be great
... and the ones that won't
