This offer is only for people who have access to corporate partner discounts (like my company), but I noticed yesterday that they have started offering the 20-inch iMac for $250 off the already 10% off most partners already get. The offer doesn't apply to any other model. No idea how long it lasts, but if you have access to a partner link (and are authorized to use it), you should grab this great deal while you can! I attached a jpg of my window for proof. Happy shopping!
