Mystery 20 dollars in shipping calculation


Recommended Posts

A mystery base price of 20 dollars is being added to shipping charges. I cant figure this out. I am using the table rate option for shipping. In fact my table rate is modified so this.


[base shipping charge]:[increment increase level]:[cost per increase level]


That of course is a weight scale that would interpret into the following


2.50:1:2.50 would mean that the initial shipping charge would be 2.50 and for every 1 pound or kg or unit and added to order after that would be 2.50 more in shipping cost. This equation works fine and does what it is supposed to however no matter what I changed the equation to their is some mystery 20 dollars always thrown into the shipping cost and I dont know why?


Here is the contribution I am using and have been unable to contact the authors.




I have tried both versions that you will see on that page and still the same thing happens. So the big question again is why is my table rate throwing in a mystery 20 dollars??
