Editor's Notes & Price Research
With the additional discounts factored in this is lower than a previous Frontpage deal from the end of April. -Corwin
Jet has the i7-6700 for $309 which you can get down to $272.20 if you use the 15% off first order plus waive free return shipping. If you stack the AMEX $10 off of $50, you'll only pay $262.20. Definitely the lowest I've seen for the i7 6700. Last front page deal was for $280, this is noticeably lower!
Sorry in advance for it not being the 6700k version
EDIT: The price dropped to $297.99 and with the same 15NOW coupon code plus waiving free return shipping, total comes down to $261.43. Even Cheaper!
