using 156c

Hi

I've found a bug with the latest zipship. Most of my postcodes are 4 digits long, however because some postcode areas are so big I split them by adding a suffix to them, eg I have 6056 charged at $30 and 6056A charged at $35.

I've just discovered that the "A" is getting chopped off and my 6056A is displaying as "6056" and charging $30.

Thanks.
