Hello,
Can you show me how did you configured your USPS shipping method through some screenshots and the dimension/weight of the product that you have on your cart, so that I can test it on my end ?
Also, I just tested it through your website and it worked fine, but I think that you have probably disabled the USPS "First Class Mail" service.

Configuration:


Product - Pumpkin Spice 4oz. Btl. with Pump:

Hello,
I just tested it on my end and it worked fine, can you try it with dimensions on your "Pumpkin Spice 4oz. Btl. with Pump" product ?
If it didn't solved your issue, can you give me a temporary back-end access to your website through a private message so that I can directly test it on my end and see from where you issue is coming from ?
Thanks.

It's fixed now, all I did was go into the configuration for USPS and hit Save without making any changes. Now it works fine.

The problem was coming from the code of the USPS shipping plugin thank you for your feedback I just fixed that issue.
