Something is wrong with usps shipping domestic firstclass

Hello, I am having the worst time trying to get the usps first class domestic shipping working. it just wont show up in the available list of shipping options. i already fixed the international shipping bugs, but they led me to my current problem. i have looked every where for the fix and cant find it. i have tried all the suggestions to fix this and nothing works. :frusty:

also now my international first class shipping is gone too..... where am i going wrong....

Which version of the USPS module are you using?

Also USPS first class shipping has much lower weight limits. The module I modified removes the first class options if the order weight goes beyond a certain limit.

If you want help you will have to provide more information about your configuration and what is happening.

For example - are other shipping options showing?
What is the order weight?
What parameters are you using to test it?
etc...

sorry bout the lack of info about the problem. here are the current settings.

  once again sorry bout the lack of info and thank you for a speedy response.

ok I i just tested the shipping with something that weighs exactly 0.375lbs and it showed up with the first class option in both domestic and international. i will admit i feel a bit silly for not doing that sooner. so i think i have to change my question to, how can i set it to ship a heaver item?

What did you have in mind? To ship more first class boxes once the weight goes over?

USPS domestic first class doesn't allow you to ship anything over 13oz. I would just enable Priority Mail for the easiest solution.

ok thank you for inspiring me to look into other weights. i still feel silly for not looking into it sooner:wacko: but its all sorted out now.
