Just picked up an r7090 from samsung with a UNIDAYS discount (educational discount). Click the link below and the the r7090 will display at $499.00. Add it to cart. Mine went into the cart at 457.00. Use coupon code P5V6WGYZC to take 100.00 off. Was able to get it at 357.00. Tried to replicate and it showed up at 415.00 after coupon. Not sure how I got the 357.00, but 415.00 is still a pretty solid price.
I know a similar deal was posted, and samsung pulled the ability to use coupons, so I marked it YMMV.
Make sure you sign into UNIDAYs to get the STUDENT discount.
