I can't send the book Illustrated guide to Home Chemistry Experiments to my kindle. At first I thought it was the size but I can send The Illustrated guide to Home Biology Experiments to my kindle and that is a bigger book.
The send ebook link has options for dropbox and google drive but no option for kindle.
Thanks for writing us, and I'm sorry for the frustration. Amazon has a limit of 50MB for sending to Kindle, so unfortunately we can't offer this option for larger ebooks. The mobi file is 49MB and unfortunately this is too big to use the "Send to Kindle" option.
Instead, you can transfer larger ebooks to your Kindle by downloading them to your computer, connecting your Kindle to your computer with a USB cord, and moving the file into the Kindle's documents folder. Let us know if you have questions, and you can find more information on Amazon's help page.
I hope this helps!
