Placing different shipping rates
I have 3 different types of poster on my website. Folded, Flat and Rolled. Folded costs £6 to send, Flat costs £12 and Rolled £8. I had set up the website and eCart when I only had Rolled posters so the default charge is £8. However, if someone is only purchasing a Folded poster then it still charges £8 and I want it to charge the £6 instead - the same goes for changing the postage costs for Flat posters. I have set up Columns called Folded and Flat and have tried a couple of combinations in the Merchandising Rule box but just can't get it to work. Could someone help me?
