Fully Functional and Accurate Shipping Calculator

- Have the shipping calculator offer USPS, UPS, and Fedex to the customer instead of having only one service option.

- Input options for separate packaging weight and product weight, where the calculator adds the product weights together then adds that total to the packaging weight when calculating combined shipping. Expand on that with option to increase packaging weight when X amount of that item are purchased. For customers purchasing multiple different items, set options to add the weights of the different products together and then add that total to an average weight of the packing weights from the multiple items being purchased.

If that could be accomplished, bonanza would have the most accurate, flexible, and cost-saving shipping options for their sellers and customers. Right now, I have to sell some items in lots, just because the multi-item discounts and shipping options do not really save any money.
