Please note that the site Baginc.com does not sell designer handbags, just "designer-inspired " ones and this is clearly published in their front page. There are no indications that it is a scam, but their payment options do not provide you much protection - it shows credit cards and PayPal but when you check out, you can only pay thru Western Union. Their business is based in HongKong but they did not provide any domain based email address or contact numbers.
We have several generic bags suppliers listed at SaleHoo (and a couple for the high end designer ones). Let me know if you need help searching for suppliers.
