[quote name='SlaughterX']And of course I would finally get those coupons in the mail yesterday, after ordering the TV... Has anyone got these coupons to work on TVs that are on sale?[/QUOTE]When the TV shows up, assuming it's still the same price now when you bought it, they should work to re-ring it with the 10% discount.
The coupon does say "not valid on prior purchases", though you have nothing to lose but time. I've had far more times than not in getting them to rering it with the coupon.
It doesn't know the item is on sale, it just knocks off 10% off the item's price that comes up in the computer.
