They seem legit and accepts credit cards and PayPal. Although they are pretty new, less than a year old - we recommend you deal with suppliers that have been online for at least two years.
They do have some popular products listed on their site. I'm not that satisfied with the contact details though, there's none except for their contact page - no address, no phone number.
If you must try them out, start by getting to know them maybe exchange a few emails and order the smallest or cheapest product you can to check their product quality.
Hope this helps. Cheers!
