The code will only work with select accounts, but it's worth seeing if your account is one of them.
Brad's Deals Editor Michael,
Select Amazon Prime members can apply the code 4KFIRETV during checkout to drop the price of the Amazon Fire Stick 4K from $49.99 to $24.99 at Amazon. Shipping is free. The code will not work for every Prime account. However, for those who are eligible, this is the best price we found by $14. The 4K Fire Stick can stream both 1080p and 4K HDR content from thousands of streaming apps. It comes with a new Alexa voice-control remote. Sales tax is charged in most states.
