How to purchase books from Amazon without Wifi/3G connection

[Amit]

As you'll know that I have purchased a Kindle wifi only model. Now I
wanted to do following things.
1. Register it in my name
2. Purchase books from Amazon

1) I tried to register it online, however since it was ordered from
shopyourworld.com it is actually registered to tarazz.com site.(which
you can say is the parent site of SYW.com)
So the only way is to connect to wifi and then using the "register"
option in kindle. I am not having a wifi connection as of now, so I
have decided to skip it for now.

2) Now comes the second part, I wanted to purchase a book from amazon.
But I was not prompted for the option to "send to my kindle" since I
haven't registered any. So I installed kindle for PC on my laptop,
purchased the book from amazon and selected "send to kindle for pc"
option and downloaded it to my laptop.
Then I connected the Kindle device using the usb cable and copied the
file from "C:\Documents and Settings\amit\My Documents\My Kindle
Content\XXX_EBOK.mobi" to my kindle device and Done !!

Cool Amit.

I also noticed that my Kindle DX was registered to Tarazz.com. I used
the wi-fi to deregister Tarazz and register myself. I have however yet
to make a purchase.
