Hi
The price is set by weight not size, so 5kg of 12mm is the same price as 5kg of 15mm.
The customer gets a better deal if they buy 10kg or 20kg or 50kg. What I would like to be able to do is make it so when the customer buys a mix of sizes, so for instance 5kg of 12mm and 5kg of 15mm, they would get the 10kg rate rather than paying the 5kg rate x2. And obviously also if they were to buy 10kg in two different sizes, they would get the 20kg rate etc. Is this possible please?
Thanks,
Lou
