I wouldnt buy from that store, it's freshly opened and that in itself is very shady. if you want to buy a fake, you will find sellers with more of a track record, there's post on "consensus on replica frames" or something like that. One user here has a really, really nice looking no name trek copy, for example, but there are many more.
Taking a step back, it's probably best to buy something that's not a fake, but you do you.
