ok. that was indeed the case. I removed Book and DVD shipping.
Also, in the weight units of the USPS Server behavior, I see this line of code:
$Shipping_PackageArray[$Shipping_PackageIndex]["WeightUnits"] = "".strtolower($eCart1->WeightUnits) ."";
I changed to oz and it seems to be calculating differently. Why wouldn't it just pick up that info from the eCart object?
And why is it that the calculation for one item is $3.16 (10 oz. item) but then for two, it more than doubles shipping price at $10.60? I can't understand that. It should be maybe another dollar or two I would think.
Sorry for all the questions, but this is the first time ever that I'm doing this.
