No worries, so lets cover your query. Ive received your files, but they seem perhaps corrupted. Am only
able to open the first one on my machine hence thats the only one I converted. Perhaps Ill send you my email address later for you
to directly send over to me. So here it is :

This is the sample file of .chm youve sent over, opened in my PC.



Converting it with the Auto Kindle Converter
you get it changed to .mobi format, one that Kindle reads.
Picture below is of the page highlighted in the PC.



Here's a picture of the same page but with a change in the font.
For .mobi files you can manually change the font without the need to zoom in.



To the next question you have, its easy, just like how shy8629 says and also posted on the first page,
You can choose any items you want from the Amazon store, even if youre not buying a Kindle unit,
it can be Anything from Amazon
Ill quote you a price for it to come along in my Kindle bulk. Once payment is collected, itll be ordered off from Amazon,
shipped to my colleagues home, collected with the other stuff there and sent over to Malaysia. On the same day,
it reaches my hand, it will be prepared for shipping or COD with you
