Forumula to total items in multiple rows

I have ~500 rows of data in columns A, B, C that is as follows, for example:

Qty Shipped......Invoice Number.......Product
14...................ZETWS..................Apples
16...................ZETWS..................Apples
19...................ZETWS..................Apples
13...................ZETWS..................Apples
36...................TWETY..................Bananas
33...................TWETY..................Bananas
38...................TWETY..................Bananas
32...................TWETY..................Bananas
21...................UWRYE..................Pears
26...................UWRYE..................Pears
23...................UWRYE..................Pears
28...................UWRYE..................Pears

Try something like this....

D1: Apples
This formula returns the qty shipped for Apples:
