Is Hobby-Genki.com legit? I just ordered something from there, but when I got my confirmation (from customerservice@hobby-genki.com) Gmail told me it couldn't verify that it actually came from Hobby-Genki.com, and I should avoid clicking any links in it.

Did I get scammed? Do any of you have familiarity with them? Now that I look back at it, my signup email from them got flagged the same way.
