There are good vendors, there are bad vendors. Be careful and do your research or you will get burned.
The best I have dealt with will resend items if there are any issues. The worst will call you a liar even with photo evidence. Don't expect to find any authentic goods on here, as that is not their game here.
If possible find some coupons to save money, that's the only reason why I'm writing this review actually. Remember to ask the vendors to send pictures of the items you plan to order, because sometimes it may not be the same as the item pictured.
