Dear

In deference to your valuable time, I would like to get

straight to the point and say that we were wrong.

Your purchase order clearly stated 30 cases. The shipment

of 60 cases was our error. Meanwhile, there are two

options available at this time; you can keep the

additional merchandise and we will bill you thirty days

from now, or we will arrange to have it picked up at your

loading dock and issue a credit to you. Please let me

know of your preference.

We will do everything in our power to ensure that this

type of error does not occur again. Thank you for your

understanding. If I can be of any assistance in any way,

please do not hesitate to call on me.
