Awesome functionality

I was looking for a shipping plugin that could define flexible pricing for different suppliers, e.g. Supplier A delivers to US for $5 and to EU for $10 using flat rates, Supplier B delivers to US for $10 and to EU for $5 using weight-based rates, so it is pretty hard to distinct pricing for all products in catalog provided by multiple suppliers dynamically. This is the only plugin that provides super clean UI and allowes me to create flexible rules using built-in conditional logic based on weights and shipping classes. Great job.
