So very new to zencart, I basically got put in charge of it and have a fully functioning website given to me.
So I have many roses which we sell on website. Origonally we were just selling bareroot roses but now we want to sell potted roses aswell. I have managed to set up an attribute which allows to to choose whether you want it your Rose product Bareroot or Potted, but now I have to try and figure out how to change the shipping costs so that it will add an extra fee to the potted attribute and that it can only be sold in the UK. We have a flat rate shipping for all bareroot roses but that was without this new potted attributes.

Also I know this is a lot to ask but is there an option so that 3 potted roses will be cheaper shipping than 1. Or 6 will be cheaper than 3 and so on...

Many thanks.
