Aside from that MASSIVE DEAL ALERT: Amazon offering 20% off (up to $100) when you use an American Express card and redeem at least 1 AmEx Reward Point, makes RX 580 8GB $148! there really hasn't been anything so far.
I have tried to grab a couple of deals myself but on another online store but the cool stuff is already sold out by the time i click on it. People are waiting to grab those deals online on these special occasions so you have to open your eyes for them and grab them as soon as you see a chance anywhere. Luckily i got the whole year hosting for my website revglue(.)com for just 4.75$ and i was barely able to grab it because the offer was online for just one day.
