USPS Shipping Module by MarcoB - RateV4, IntlRateV2 - Support Thread

I need help figuring out why my shipping charge is 3-4 dollars higher than usps.com rate quotes. No matter how I change around shipping/packaging section tare weights and variables I cannot get within atleast the dollar range in accuracy for the usps shipping module priority mail. all packages are set up to ship for the same price since I only sell 4 products on my website, all ship in the same size box. Its set up really simple, but I cannot get the atleast within the dollar range of accuracy, its off 3-4 dollars.

What are the settings within the module?
What are the specifics of what you are shipping? weight, size, value, etc?

I'm struggling with what defines a USPS First Class Mail Package. I ship small, light items and have been using some test items to find my issue. I'm using a tare of 10 (10% weight & volume (?)). I have one item that weights 0.125/0.1375 pounds and is 11.3/12.43 cu. in. which allows the First Class Package option. But another item is 0.125/0.1375 pounds and is 11.7/12.87 cu. in. and does not allow First Class Package. I don't see anything at USPS that constrains on such a small volume or weight. I'm sure I'm doing something wrong, any help would be appreciated. ZC 1.5.1. BTW: This is a much-needed add-on. Well done!

I have matched the weight on usps website for a quote. usps.com quote is telling me the same zipcode and weight is 9.50. my website is saying 12.40

Unless I'm reading something wrong, your settings seem to indicate that:

the smallest package you will ship is 1 pound
Small/Medium tare = Add 1 pound
Large tare = Add 2 pounds

Also, you are using the USPS shipping module, not the USPS Shipping module Ratev4-IntlRateV2 which is the subject of this topic.

See if this helps....

\includes\modules\shipping\usps.php

Around Line 187, Edit the coded volume of 12.5 to whatever you want to be the max volume that you will ship via first class.

Code:

---

'First-Class Mail Package'=>
        array('id'=>0, 'maxWeight'=>0.8125, 'transitReq'=>'StandardB', 'maxGL'=>108, 'maxLength'=>'', 'maxWidth'=>'', 'maxHeight'=>'', 'volume'=>12.5, 'regOnly'=>0, 'commOnly'=>0, 'size'=>'', 'fcType'=>'PARCEL','container'=>'', 'service'=>'FIRST CLASS'), //CLASSID="0"

What happens when you set the tare to 0:0 for small/med and large boxes instead of adding 1 or 2 pounds?
What happens when you increase your largest package that you will ship to a much higher weight than 1 pound?

if I set my products weight to 1 pound. and my small to medium to 0:0 and large to 0:1, I get 12.40 as my priority mail charge. now, this should be sending the information to usps that my one pound package is shipping priority mail. why is usps module quoting 12.40, and usps.com is quoting 8.50? Because there is no flipping dimension size. its giving me some random ###### rounded up number from usps because it has no clue what the box dimension size is.... the box dimension size has everything to do with how much usps charges you, along with weight. why do these modules go by weight only? this seems like a SEVERELY overlooked variable. it seems with this module, you cannot go cheaper than $12.40 for a large priority mail package, and no more than $6.20 for a small-medium priority mail package. no matter how much I mess with the weights of my products. I have my own boxes Im shipping in, I enter the dimension sizes into usps.com, I enter the weight, select large box, select the zip code and then select the priority mail option, Bam.....4 dollars cheaper then usps shiping modules quoting me.
