I found a very cheap deal on an 8gb kit of corsair ddr4 2400 and a corsair k70 on amazon. When i checked the seller profile, there was no info on the reliability. I am wondering is these deals r legit or if i should not spend my money on this and buy it from the official website. Please respond as soon as possible as i want to but everything before cyber monday, and want to spend a minimun amount of cash.
