[ic] Shipping Question - Referencing Rate and Zone Files?

[Nolan & Lori Hostetler]

Hi everyone,

This is my first Interchange store.  It's just about ready to roll, but I'm
hung up on Shipping.  The store will use the following shipping options:
Priority Mail, Air Parcel Post, USPS Flat Rate

Starting with Priority Mail, here's what I did:

Using the "Ground.csv" file as a model, I created "PriorityMail.csv" with
all of the current priority mail rates for each postal zone.  Then, I
created "972.csv" as the postal zone file (which matches the zip code to the
zone).  Next, I went into the Admin. area of the UI, and in Shipping,
created a "USPSPM Priority Mail" method.  Calculation is done by weight.

So, now that this is all set up, how do I enable Priority Mail to take the
receiver's zip code and refer to these weight and zone files for the correct
shipping amount?

Thank you! --Lori
