Newegg End of Summer Blowout Sale
Hopefully this link works for you, sign up for the e-blaster newsletter and their shell shocker deals!
Also check Amazon.com and tiger direct for sales and lower prices, and don't forget if you have a micro center near you, you might be able to save a lot on the CPU & Motherboard if you use them - in store!
This is my take on parts shopping (just finished a new build last week):
Newegg : Best for everything you need for a new build, but might be slghtly pricier than amazon and also you might have shipping costs to consider.
Amazon: If you have prime, well you are in luck, free 2-day shipping and they are much more reliable than any other online retailers, also returns are much easier and hazzle free! (I'm a fan of their return policy!)
Micro-center: If you have one near you, they will have great deals on core components and other stuff from time to time, actually they have a monthly special catalog, if you find what you want in it (I did find my CPU & MoBo combined for at least $70 less than what I could find anywhere online), then you will save quite a bundle!
All the best!
