Summing values in a range against specific text

i have two columns. col A has customer name and col B has amount of sales.

A B
aa 10
bb 15
aa 12
ff 08
bb 12
aa 10

i want to have total of sales for each customer. col A has many customers which appear many time in col A.
how can i have individual totals.

thanks

hi!
=sumif(A:A,"aa",B:B)

or

=sumif(A:A,C1,B:B)

assuming that the customer name is in C1
