First Class Shipping USPS weight problem?

[ecowraps]

With First Class Shipping as my only option (yes, I'm set up for API), I get this -

-2147219434 - First Class mail must weigh 13 ounces or less.

My product's weight is set to 0.187 which is only 3 ounces.

If I have Priority, First Class, and Parcel selected as methods of shipping, Priority and Parcel show, and not First Class.

Anyone know a fix for this?

What is the Tare set to in your Configuration ... Shipping and Packaging?

[ecowraps]

It's set to 0:0 . I'm not quite sure that all that means.

My husband went in and set the weight to oz. since this is what we primarily ship. 3-12 oz items.

ok thank you

I'm still not sure how to get this to work. It's driving me nuts, and I can't open my store until it works.

How about posting a real Ship from and a real Ship to address and we can look into this more ...

What version Zen Cart?

Clean install or an upgrade?

Look at the file:
/includes/modules/shipping/usps.php

on your server ... what is the line that starts with:
* @version $Id: usps.php
