I had to laugh at this one!!!  PBS estimated the weight of "I Know This Much Is True" by Wally Lamb to be 8 oz.  Anyone who has read this book knows that is definitely NOT true!!!!  Try 1 lb 10 oz!!!  lol.  I double checked the ISBN number to make sure they matched....they do.  I'm glad I checked....I guess it would have been returned to me for postage or the receiver may have had to pay the extra postage!

Whenever you see that a book weight is wrong in the listing, you can submit a Data Edit to fix it by going to the book details page, and clicking on More Options button on the right, then choose Edit Book Data link.

(While you are editing the book's data, you could also supply any other data that may be missing at the same time.  The Book Data Corrections group will MUCH appreciate that!  The more complete a Data Edit submission is, the better for everyone.  And since Data Approvers attempt to try to find missing data when they get a submission, finding missing data in advance for them will help the edit get through approvals faster.)

I will do that, thanks!

Thanks Sianeka for the info! I am constantly coming across books listed as weighing 4 or 5 times what they actually do! From now on I will be one of those submitting corrections.

When you enter the weight, the system wants the book weight rather than the wrapped book weight.  (When printing postage, the software adds a bit to allow for packaging.)  And it's asking for the weight in pounds, rather than ounces.  So divide your number of ounces by 16.  And thank you!

And if you run across one of those listings where the dimensions are 20x20x20, and the weight is 20 pounds, please, please correct it.  It must be the default data on some site, and the listings are imported here, I guess.  But it's better to have zero than 20 pounds.

I have found that it is a goog idea to weigh ALL of the books that I send out because a good 30-40% of the weights and postage estimates that the site prints are WRONG.  They are about as likely to be long as they are short, though not often grossly so as the example above, but often enough difference to change the postage requirements, often by quite a bit.  I used to send corrections to the system, but found on several occasions that the ones that I changed didn't actually get changed in the system when you went back to them a second time later.
