I would copy their current return policy. Keep receipts of your purchase. If they don't send you a receipt by email, immediately call your bank to cancel the purchase. If you return the item, take a picture of it, and get a tracking number to show that they received it.

Worse case scenario.

Here is a blog from sitejabber on getting your money back. Be careful. Sometimes companies try to keep you waiting, so it is too late to get a chargeback. Also, sitejabber gives good advice on which credit card companies will give you your money back. If the company uses paypal, don't trust it. Paypal is a great way for companies to scam you. Since the purchase is through a third party it is more difficult if not impossible to get your money back.

Liz - it doesn't look like a legitimate site. The prices are too good to be true, among other red flags. I'm glad you asked before buying from it, though. You don't want to get into a situation where you have to file a dispute.

Yes, it's almost impossible to find THE ONE. LOL
Some have good LV, but not so good Chanel or Gucci. I just wish there's one that supplies ALL good quality bags of all brands. Am I asking for too much?;-)
