My problem is that when my shipping estimate, or actual, comes up it always charges for my biggest Priority box, or an outrageous Priority amount, for something I have designated as say ".25" in the weight section.
I figure that the cart adds up the total weight of the items in the cart, and then calculates it through the USPS module, but it always goes to say Large Flat Rate Box and charges for that rate even though I have settings in place for smaller parcels, First Class Parcels, etc. I can't find out why it does this.
I need to be able to incrementally go up when things are added, and have a few options for shipping. Say five items and a Medium Flat rate box, or one large item and a Large Flat rate box.
