I cant seem to find it anywhere on ASUS ROG website. I saw this laptop at Micro Center priced at 749$ at sale. It looks really good. Would it be a good idea if I should buy it or not?As it has 8GB DDR4 RAM, how could I be able to upgrade it. and Also...

I have been looking to buy ASUS ROG G751JT-WH71. The best deal available is 999$ at ASUS Store but is Out of Stock. When do I expect it to show up?

I have been planning to buy ROG G751JT, Where could I find it at the best price. Does ASUS offers any coupon code or something? 
