It's been proven they are a bunch of crooks.
They sold a whole bunch of defective S5's on here. They don't repair or refund fully:

Also suspect they have people working on OzBargain to sell their products. 128 upvotes / 0 negs (until i negged) for what was an entirely defective product. See last few posts when people received it - completely faulty firmware, GPS not working, mobile not working.
When i have time will send a letter to the ombudsman.
Never buy anything from them despite all the deals, so can't comment. With online sellers, it is really an issue if you have warranty or defective products. Have good experience from eGlobal, shopping express and Kogan though a lot of peoples seem to complain about Kogan.
