I have a lot of light weight items to ship, some weighing fractions of an ounce. It's silly to send these items by Priority Mail, so I've been trying to set up USPS V4 First Class Mail as a less expensive alternative for my customers.
I've set the weight and min/max settings many ways, but the shipping method never appears.
The documentation does not really suggest how these settings affect the visibility of the shipping method during checkout.
For example, I have a product that weighs less than an ounce, and I set the weight as 0 min, 0.5 max so a fraction of an ounce should trigger the First Class Mail method, but it does not.
I attached one of my settings here. Can anyone suggest what I may be doing wrong?
