Hi @mregesi93,
Thanks for reaching out.
Please be aware that our free USPS plugin allows for shipping cost calculation based on the cart weight and destination.
The USPS PRO version calculates shipping based on cart weight, dimensions and destination.
May I kindly ask you to turn on the Debug Mode? Then please copy all the data and post it in the reply.
With this information, we’ll be able to determine the live rates calculations and find the solution for you.

For example, it says that the 16oz body butter costs $3.75 to ship while the 2oz body butter costs $8.15. The zip code isnt the issue because even if I use the same zip code it still says that more costs less and less costs more.
Thank you for posting the debug mode notices. If I understand your shipping scenario correctly, the oz refers here to the volume of the products in the cart, not the weight.
In that case, the volume shipping calculation is also exclusively available for our PRO version.
To ensure if that’s the case, please use our free demo site, add your USPS User ID in the General Settings. Then please verify if you’re getting the correct, volume-based shipping rates with our USPS Live Rates PRO plugin.
Kind regards,
Piotrek
Well the oz refers to the weights. The 16oz should weigh 1 lb and the 2oz should weigh 0.125lb but the system charges 1 lb as less than 0.125lb. The number of pounds or ounces should affect the cart weight but it doesnt. So more more weight is costing less.
OK. Thanks for the additional details. To find the solution, I’d like to ask for a temporary admin access to your site, so our developers can look into it.

Please refer to this forum thread, so we can connect the case in our support system.
I’m marking this topic as resolved for now. If you’d like to ask about anything else – please open a new thread or email us at https://octolize.com/support/
