DHGate is great, especially for classic shirts. Got my 1998 R9 shirt for my 6 a side this week, unfortunately I'm still carrying my holiday weight.
I think I might have to get the real thing for this one though, don't quite trust the fakes when it comes to subtle prints on the shirt. The bruised banana relaunch fake I purchased a couple years back was a disaster.
This kit broke the record in day one sales for any Arsenal kit launch apparently.
