write a letter to your friend and say with them to help you something

Dear V!
I am going to have a birthday party at 8pm on Saturday. Can you help me to buy something? I need two bunches of bananas, three kilos of oranges, ten mangoes. Can you bring them to my house before the party about one hour. Can you help me? Please let me know as soon as possible.
Yours,
T
