Online Purchasing (Part II): Biggest Purchase

In the other Online Purchasing post I comment on how Ive bought computer parts over the internet, these parts added together and purchased all at once came to somewhere between $400 and $500. This is probably the largest purchase Ive ever made online, but how high would I go? Probably not much more than that. Once you get above the $500 mark you start getting to items that I would have to see in person before I would purchase them, like a car or television set. Although my parents did buy a truck through E-Bay for somewhere around $14,000 a while back. The one thing that I think of that I would be willing to purchase over the internet that would be above $500 is a travel package of some sort, with the plane tickets, hotel reservations and whatever else comes in a travel package. Another thing I MIGHT consider would be a prebuilt computer, but why buy it prebuilt when I can buy the parts and make it myself for half the price.
