This is a Furla thread so you are not highjacking anything. Unfortunately I can't see the difference between a real one or a fake one. After buying a lot and scurrying around in outlet centres I do feel the difference between a real one and a fake one.
If you have a particular bag in mind, people can help you in the

The only advice I can give you is always buy from the furla store or a webstore that you know is legit. If you don't want to pay full price wait for a sale. A 20% discount for something you really want is nice. If you don't mind on missing out, sometimes there are 40% discounts.
