I am using AbanteCart version 1.3.4.

I need to add a package tare weight to each shipment to make the shipping rates accurate. For example, the average weight of the shipping boxes we use is 0.3 pounds so I need to add 0.3 pounds to the weight of each order before the shipping rates are calculated.

I also need to add the packaging cost to the shipping rates. For example, the average cost of the shipping box, packing peanuts, tape, and label that we use to ship an order is $1.00. So I need to add $1.00 to the cost of each shipping method.

I do not want to use the handling fee option that customers can see on the checkout page because these are not handling fees. These are shipping weights and shipping materials costs, so they should be included in the shipping rates that customers see and pay.

Is there a way to add a tare weight to orders in the AbanteCart admin area?

Is there a way to add the packaging cost to the shipment rates in the AbanteCart admin area?

Or has anyone figured out how to add to or edit the code to accomplish this?

I am almost done migrating a site from a different e-commerce platform to AbanteCart 1.3.4 and I am testing the checkout page and noticed that the shipping method prices are not sorted from low to high. On this site, 99% of buyers choose the lowest-price shipping options. Therefore, I would like the lowest-priced shipping option to be listed at the top of the shipping carrier options list.

I can not find a way to sort shipping method options by price in the Admin area. I am using the USPS and UPS shipping extensions that are included with AbanteCart version 1.3.4.

Is there any way to sort the shipping method options by low to high price either in Admin settings, by changing or adding to a code file, by using an extension, or???
