For $8 in shipping on a $110+ board i really wouldnt consider switching over to a new site that i havent heard much about, they have limited selection, pricing isnt any better than newegg, but i bet the shipping speed is worse. I just ordered something on monday at noon with 3-5 day shipping, its here now(for those keeping track thats less than 48 hours)
Also, im not sure where you get the idea that ChiefValue.com is a newegg sister company, but i can tell you simply by looking at their website that they have no relation, their website is of much poorer quality than neweggs, their about us and contact us page lack critical information making them seem sketchy to me.
Oh, and since this is your first post im reporting this as an ad.
