That's alot of Mickey D's
Because I live <30 miles from the Egg's SoCal warehouse, I can recieve orders in<36 hours=scary fast. BUT, Newegg does not have the best pricing and/or shipping...Often.
Yes, eWiz is a very trust worthy reseller. My last order took 3 days w/basic ground shipping.
TIP: If you order a PSU from eWiz add something you need to the order, that way they will have to double box it. This will make for a safer transit to Texas.
