How to amend the shipping fee on an active listing?

[bilobatron]

Hi, 

I'm having a hard time amending this shipping section for my listed item. Right now the dims AND weight are incorrect (e.g. the height and depth should be 30" and 15", not 3" and 5" -- and the weight is 10 lbs not 3 lbs).

I now have an offer for it and I'm afraid if I accept, I will lose money on the incorrectly calculated shipping fees. 

Any help is appreciated! Thanks

You won't be able to edit the shipping section as long as the Offer is pending.

You will have to decline their offer, then make the changes. You can explain to the buyer in the Offer box why you're declining it (ie, an error on shipping costs)
