When creating a listing, and you intend to ship with a bag, for the dimensions do you put (for example) 12x10x1 or just 12x10 and leave the last field blank? Or what? I can't find an example anywhere. Thanks in advance to all who respond.
You can't leave it blank. It's OK to just estimate, and enter "1". For eBay postage labels, the dimensions won't affect the postage cost unless your package has (1) length over 22 inches; or (2) volume over 1 cubic foot (1728 cubic inches).
