I have bought some Replica Nokia 8800's from DH Gate. You need to look at all of the sellers feedback very closely and read every comment from past buyers.
I emailed my supplier several times asking questions about the phone and different ways of payment.
The product itself was amazing, the box the phone came in and all the accessories were very high quality and i sold them as replicas and recieved very positive feedback from my customers. I was making very good margins for a couple of months until the rest of the market jumped on my bandwagon.
Research, research, research.
