They are scamming you, and you will not receive your items, and what you do receive will be cheap, tiny, and you will lose your money. They do not return, they do not email you back. I PROMISE YOU WILL BE SORRY AND LOSE YOUR CASH.
If it is too late and you already bought, Pay Pal will not help you either. You need to call your credit card/bank and tell them about the fraud, then let them handle it. DONT BUY FROM CHINA ETC. YOU HAVE NO RECOURSE AND YOU WILL SPEND HOURS TRYING TO RESOLVE THIS. If the price looks too good to be true, it's because it is! Nothing is that cheap that is of value!
