Hello. I am creating a site that sells liquids. I have some very advanced shipping rules and I am wondering how I can go forward with implementation.
1) I am not scared to write my own module...but I need to hook into ups shipping quotes. any advice here?
2) how do I define another shipping type other 'small package'
3) i need to change package size based on the total amount ordered
4) I need to add hazardous shipping fees on certain products.
5). Some products can not be shipped with others and will require an extra shipment.
6) i need to make sure I can do multiple packages in a single quote
This is what I need todo shipping correctly.
