tough call but it is hosted at most likely China and owned by chinese company http://reports.internic.net/cgi/whois?whois_nic=picktrend.com&type=domain
There is only one way to find out If I were you I would use a site that already has a good name for itself.
I've bought from sites like these in the past, theyre based in china and the good are fake....If you want to buy fake goods, they are usually very reliable and 80% of them are honest. This looks to be an honest 1 but you should try a sample order, maybe just spen $20?
im not sure if that's a scam, but as long as you got involved that site, and they failed you're expectations that's the only time you can tell that is a scam...
maybe you should clarify that in the beginning, people don't know what you mean when you question a site being a scam without first mentioning the reason
