you are either an O-member or if you sign up for their VISA CHASE credit card (which gives you a 3 month free trial membership to the O-club IIRC).
Also, by signing up to their credit card you get 3 points per dollar (basically 3% off and 1% off anywhere else you use the card, in ohter words the same as the Amazon VISA Chase credit card) which when you reach 2500 points can be used for a $25 overstock giftcard.
Thought I'd post this since Ipods are one of the few items out there that hardly ever go down in price or is discounted much either online or at B&M. The cheapest I've seen this online (apart from eBay auctions etc.) has been $289.99 and my local Walmart had the same price last week.
