We’ve just updated the premium addon, Dukapress Shipping Pro to use Weight Classes as the shipping rate. What does this mean? This means that as you create your custom locations using Shipping Pro, you are now able to set different shipping rates for different weights instead of one rate as before. This is because we realise if it costs $2 to ship 1Kg it does not necessarily mean that it costs $4 to ship 4Kg. Now you can define this to be exactly the way you want it!
