Right off the bat, I should disclose that NCIX advertises here at TR. However, I've been buying PC components from NCIX for about a decade now, which is much longer than the retailer has had an affiliation with the site. For me, one of the biggest benefits to buying from NCIX is being able to pick up my orders at one of several local retail locations in and around Vancouver, BC—often within hours of adding items to my online shopping cart. Now, US customers living in the LA area will have a similar option.
NCIX has opened a new distribution center at 21788 Garcia Lane in City of Industry, CA. Ordering from NCIX's US site should give you a warehouse pickup option that will eliminate shipping costs. I'm seeing a 1-2 day wait listed for for that option, so you might not get as quick of a turnaround as I'm used to enjoying on NCIX's home turf. The site also offers free US shipping on orders over $50 and under 200 lbs.
