Just bought my jersey for the season
Found a website with 30-70% off on the new 2014-15 kits. aliexpress.com
They have buyer protection and full refund guarantees should your order be wrong or not get there within the quoted time. Also, if your item is wrong or mismatched with your order, you have the option to keep it and receive a partial refund.
It is one of those Chinese based shipper sites, but I have found them to be highly satisfactory in other buys I have made. I bought a Nolan Ryan Astros throwback for around the same price as you see on the site I link from a separate site. Also an Erik Dickerson jersey. Both authentic, both still had the $300 manufacturer price tag on them. Not saying that these are the same, but I have never had a problem with these sites.
