Changing Package Dimensions of an Active Listing

[hamiltor57]

I can revise other information but I can't seem to find a way to change the package dimensions which obviously affects shipping charges.  Any help would be appreciated.  Thanks!

Buyers bid on the item with the information in the listing.

How fair would it be to buyers that have bid, if you go and change the shipping.

You can't change it.

If you made a mistake, you'll have to make up the difference.
