Hmmm i had a very very very bad service with goodluckbuy they took 15 days to process the order
15 days just to process it, ie change the order-status from 'processing' to 'confirmed'
, thats a very long time. It was my first time buy from GLB(goodluckbuy) hence i thought there might be some process. Hence i got in touch with their live support i.e. Live chat. Which is just non-sense you just sit there but no one will come and help you out. Then thought that there might be very heavy customer so might not be getting to a CS easily so lets write a mail. To which there was no response ever.. But after 15 days i got a mail stating my goods will be shipped and there was a date mentioned.
So in all it was not so very good experience for me, yes prices are cheap free shipping is offered (but i will suggest dont go for it as they dont provide you any tracking data) but then shipping and the customer service was awfull..
I did went through a lot of review on RCG too but found mixed review about GLB hence cant say anything about it. You can ask rcelectro owner (Vivek) he very does sometimes buy from GLB (as he told me last time when i asked him)
So not so good review from me..
