How to combine repeated data to give a total value

I've a speadsheet of product sales data.
The sheet shows sales by product code and the quantity/value per order reecieved.

Is there a way for me to add all of the values per product code to give a total for that piece?

See the attachment for an example of what I want to do. I want to somehow run a formula that will automatically collate the values per product code.
Eg.
Item no. 53040 is repeated 13 time - I'd want to just show this item once with the combined quantity of 69 and value of 222.18

I have a lot of data so need to find a way to do this quickly and easily if possible?

I Think that wil do the job thanks. I can then just copy and paste values then remove duplicates from column A?

Simply copy & paste column A to another column, "Remove "Duplicates" and amend "Special_k" 's formulae to reference the new column.

What would the new formula be if I did it that way John?

=SUMIF($A:$A,$H2,C:C)

and

=SUMIF($A:$A,$H2,D:D)

where column H had your unique list

Thanks to John and SpecialK - problem now solved.
