Simply do NOT!
I made a purchase on March 2015 and paid for an express shipping. After two weeks I was contacted by them saying that they did not have the model in stock and I could either get a discount or select another model. I decided to take the discount. I did not hear from them and wrote an e-mail at the beginning of April. I received the same response: they would let me know as soon as they had them on stock. I waited again a couple of weeks and at the end of April I asked for a refund, to which they agreed. However, they did not refund me. According to them, they tried to refund me but my Bank would not allow it (I know, it makes no sense). I checked with the bank and there was no such action taken by them. I asked for a proof of refund, which of course, I did not get. Then, I was offered the option of a check refund (which I accepted) and again I did not receive any because it would take one month to approve the check inside this company (sure, they are such a huge company). I waited one month, and they did not reply to my e-mails anymore. I started the procedures with the Bank which contacted VISA. After almost two months from my complaint with the bank, I finally received the money back today.
Stay away from them! More people should review this website and give their feedback. By doing so, we will save other people time and money.
