Amazon is offering select lucky customers $40 off pre-orders of the all-new 3rd-gen Fire TV Cube by entering promo code 4KCUBE during checkout. Once again, this is only for qualifying customers so it will likely not work for most people. Needless to say, at 29% off the regular price of $139.99, this is a fantastic deal considering the Fire TV Cube was just announced yesterday. I’ve asked Amazon for information on what makes someone qualify for this offer and will report back if I get a response. If you’re on the fence about buying the new Fire TV Cube, I say give the promo code a try and if it works for your account then I suggest placing your order before it’s too late and deciding later if you want the device. The new Fire TV Cube doesn’t ship until October 25th so even if you order now with this promotion, you’ll have nearly a month to decide if you want to cancel the order or not.
