Several things. They claim to be in business online since 2004, but a whois check shows that the site was just registered in may 2008.
A quick check on the 'wholesale forums' shows that customers are saying that they have received some nice bags but were plainly just good fakes.. Also bags arrived very poorly packaged, as several bags were being stuffed into one small box with no tissue in bags to maintain shape...
In addition and most importantly, amourfashion's policy clearly states that you cannot put the bags up for sale on ebay..If you do they will cancel your account and no longer sell to you...That's a pretty strange policy...
Just because they are not getting complaints against doesn't mean that the bags are genuine.
There is a huge market in people knowingly selling fakes to their customers, and things like designer name hand bags are right up there.
Try jimmy's liquidation group, they do some hand bag buys so he should be able to put together a deal for you.
