update, found one.
got an email back from northern, said i lost my coupons, they told me one was 196456 for a 20 off 100. they said thats the only one they had....
took me one try and i nailed a 50 off 250.
196450 is 50 off 250 order. one problem is that it shows online, but its a faulty code in that it doesn't take the amount off the order. you need to call in to have them take the amount off, guy said theyve had more than a few problems with some discount codes today so shouldn't be an issue. by the time anyone uses this one it should be fixed
