So, how can you find out if a website is scamming you?

I WAS going to order some replica Air Jordan V’s from Old School Sneaks but I’m a bit dubious to be honest. There are a few other sites selling similar stuff which have been outed as scam sites, but I see no mention of Old School Sneaks. On the other hand, I can’t find a customer reference (there are some on their site but I’d rather read it somewhere else).

What REALLY gets me is that I’ve never been that bothered about this stuff in the past, usually it’s only after I’ve clicked that button that the (admittedly small and distant) bells start ringing in my head.

I guess it’ll be covered by the credit card company if it IS a scam but how do you prove it?
