I just bought my n93 from plemix.com. I saw someone had posted saying it was a reputable company. But they only take paypal, and my payment was refunded. I sent an email and they responded "we never received an order form". I asked if it was something I did, and they replied with "please try again". This is at 11:00 pm WST. Who works at these hours? Kinda made me suspicious. Should I be? Has anyone bought from them?
