If you can wait 1 month, the "Black Friday" sales, (day after Thanksgiving in the US), always seem to have extra cheap laptops. Most will be "door crashers", where a superstore has only six laptops at $300. Some deals might even be available online - last year there were some that were available online on Thursday to avoid the crowds on Friday. There will be plenty of rumor threads about those sales starting soon as details start leaking out.
