Shipping Classes Question

Hi there,

Trying to get my head round Shipping. I can’t find the answer to this so thought I’d ask here 🙂

Say I have various different products, these having different flat rate costs for postage. Shipping Classes seemed the most straight forward however I have hit an issue.

If one items postage is £2.50 and someone order 3, it can’t be 3 times the postage and it can’t be a set amount no matter how many someone orders.

Is there a way so that if someone orders 1 it’s £2.50, if the order 3 it’s £1 more using classes?

I hope I’m missing something obvious here 🙂

Many thanks.
