You can do it with a pivot table but you need to determine how many unique
deiveries you had. To do that I added 2 extra columns to the source data so
that I ended up with this...

Post Code Date Deliveries Unique
A 1.00 A1 0.50
A 1.00 A1 0.50
B 1.00 B1 1.00
B 2.00 B2 1.00
C 3.00 C3 0.33
C 1.00 C1 1.00
C 3.00 C3 0.33
C 3.00 C3 0.33

The formula in C2 is =A2&B2
The formula in D2 is =1/COUNTIF($C$2:$C$9, C2)

Here is the pivot table...

Post Code Count of Date Sum of Unique
A 2 1
B 2 2
C 4 2
Grand Total 8 5

I have got a problem where I need to work out how many deliveries were made
in a month of sales. I am doing this by if the postcode and the date of
delivery are the same on two separate orders they have gone together on one
van and it is counted as one delivery.


Example

POSTCODE DATE POSTCODE ORDERS DELIVERYS
A 1 A 2 1
A 1 B 2 2
B 1 C 4 2
B 2
C 3
