Hi, I know this question is a little repetitive, but I can't find the exact
answer.
I have a sheet that has a list of all style numbers that we offer, how many
were sold, and the dollar amount. The info is from 6 different shows, so i
have duplicates. How do I recognize the duplicates and have the dollar
amount and quantity added while deleting the others?

EX
A B C
ES5666 34 $400.
ES5666 26 300.
ES8900 5 150.

I need it to look like this.....

A B C
es5666 60 700
es8900 5 150
