I'd guess more like 2-5 months depending if they got tied up in customs.
Still the site even says TC9 motor with copper shorting ring. Hard telling the quality of coil, suspension, or cone, but still WTF, just motor and frame is worth well over the 30$ price tag assuming you're not getting low grade steel or ceramic in the motor.
It would be really crazy if they had the aluminum cones at that price.
Also picture looks to me like 10" frame which is suspicious, and of course the link to the 18" 5100 with the NRT motor or 8$ a pop definitely strikes me as too good to be true.
Good luck to anybody who tries to order any of this stuff, if you manage to get some 5100's for 8$ I'll gladly offer you 100$ a pop for a dozen, for a pretty nice profit to whoever wins this gamble.
