Postage for multiples of the same item not working

[nsix_54]

Hi, I listed a Buy it Now with 3 of the same item as the quantity available. Someone has bought 2 of them but ebay has only charged them 1 postage fee. The cost to send 2 of them is more than the single postage that ebay has charged as it takes the weight into the next band of pricing. I'm not sure how to set up my listing so that if the buyer purchases 2 of the same item the postage increases. I could only see how to do this across all listings which I don't want to do, I just want to do this for specific listings. Any advice will be gladly welcomed.

If you correctly entered the number of items, thevit is up to you to complete the TWO PRICE boxes, which the takes care of multiple purchases.
