I just bought Asus EEE PC 900HA (8.9" display, 160GB HDD, 1GB DDR2 MEM, Atom 270 CPU, Win XP Home)
Regular Price on ebay was $349.99 with free shipping from a number of sellers.
10% coupon on ebay (CFALLSAVINGS10P) - $35
MS Live.com 30% cashback program (free) for ebay paypal purchase - $105
my total was $239 because of $29 California sales tax.
You'd need to sign up for MS Live.com cashback account, and used http://search.live.com/results.aspx?q=eee+900ha&form=QBLH&qs=n
live.com search for ebay items.
- Edit -
URL Did not give me direct access to ebay with cashback logo. I think the top "Sponsored site" would do it. It's important that you see
logo to be eligible for 30% cashback on buyitnow purchase from ebay.
