There seems to be either a glitch in the system or a crazy sale going on at www.nokiausa.com

Add the N810 for $229 into your cart and get an automatic 25% off and then use the coupon code CARTP409N to get an additional 10% off.

The final price in my cart came out to $148!!

The 25% off seems to be for the entire product line so phones like the E71 are around $233 and N97 preorders are around $500.
People over at howardforums are getting confirmation emails and their cards have been charged.
