i know that this not a real support question but i think maybe your Plug can also handel my need.
I sell Product between 0,1 Kg and 2,5 kg the difference between tham is
that some have to shipped Express because they are frozen and other not.
So there can be a Produkt with 250 Gramm what is frosen an so there has to be express shipping and a other one are not frozen teh weight is also 250 Gramm
Because my englisch ist not so well i´m not sure If you could understand my needs.
The question is, do you see any chance that you plugin or Woo it selfs can handel my request ?
