For you skiers and boarders there is a warehouse sale at river rock casino for orb and arson apparel. Even if you don't do that you can still pick up cheap winter jackets, pants, gloves etc.
It says 40-70% off on all stuff so you might find something decent.
Starts today 12pm-8pm then goes until sun.
To find it just go to the reception desk and ask about it. Or follow the signs >.>
