If you can't afford to honor coupons, then don't advertise them. All coupons are completely valid as issued, I think. Dell has deep enough pockets to sell the phones as the final price ($441 + tax). Don't be a bunch of d-bags, Dell. Do the right thing and quit f'ing with your customers. And IF you do cancel, you are complete a-holes for not doing it within a business day or two.
