I've been waiting for the Silver Anniversary Edition to pop-up at Best Buy so I can get 20% off with my GCU. The thing is though you CANNOT get through checkout on your Desktop, you need to go through the mobile site and then you shouldn't have any problems with checkout.
$48 (pretax) after 20% off.
Edit: Updated with direct link to the mobile site - wouldn't direct correctly until I put it in a quote.
Edit 2: Regular site works now, added that link too.
