jmebonner is right about shipping, some people overcharge. Unless it's better than ground, it shouldn't go over $25.
I shipped out a 15" Viewsonic in it's original box, inside
another box with packing peanuts and it was $23.34. This was with Delivery Confirmation and insured for $225. Priority would have only been $4 more.
The only way shipping on eBay should be more is if they are charging more and getting lower bids. The total price is the same, but this is a way "around" eBay getting a % of all your money.
