Internet Purchases

I read this article the other day discussing internet purchases and how good they are, namely because :
a) u don't think about what u're doing
b) if u're buying clothes u can try them on in your own homw
c) u can buy things that may not be directly available to u

Reccently i've taken to buying a lot of books online.
Mainly because it's cheaper, i can buy things that aren't available to me in Australia and it takes a lot less time than if i was to order it at a bookstore.

Plus the fact that i don't really think about if i want it, and just do it is a plus... my credit card bill may send me into the negetive though...
