Well said.I've never put my trust on purchasing high-end stuffs online.It maybe said "Authentic",but a "Replica" look just as good.For the satisfaction of your every dollars credited,get it from the rack.I will say no because 90% of the designer goods are counterfeit. Even if it's a authentic, it might be from the grey market.
Be patient, wait for the sales. It's only at that point you can be 100% sure of the authencity and walk proudly carrying it
