If you total for every change in address then each distinct address would be
the same as each Total? So
=SUMPRODUCT(--(ISNUMBER(FIND("Total",A1:A300))))-1
the minus 1 at the end is for the gran total that shoudn't be counted, or
just copy all the addresses somewhere else and use a formula on thos addresses
=SUM(1/COUNTIF(A2:A300,A2:A300))
entered with ctrl + shift & enter
