At the risk of sounding like a broken record, I'll share this again, as it bears repeating for anyone who hasn't seen it.
There is a BUNCH of free scam-detector sites, on which you can paste in the web address of the suspect site. I did a general Internet search (I don't "Google" and refuse to allow a general Internet search to be hijacked by the idea that Google is the ONLY way to search - it's the way NOT to search) and picked one each time I've brought this up.
This link is the one I picked this time and I used Artful Bullet's address (for this thread actually) to test. Comes up "potentially legit." All of the too-good-to-be-true sites have come up with something like a score of ONE through FOUR out of one-hundred possible point score and it lists all the reasons why, one of which is always that the site it literally only days old.
Check if Artfulbullet.com is legit or scam, Artfulbullet.com reputation, customers reviews, website popularity, users comments and discussions.

You don't have to be stupid to fall for these scam sites, just tired, over-tasked, trying to squeeze in an order while you have a chance, etc.
Many of these sites have gotten wiser and are offering powder at more realistic (if not reasonable) prices, just a few dollars less than legit sites are offering.
All that said, several sites I've purchased firearms or handloading supplies from since 2008 or so were fairly new (at least to me) when I ordered, had significantly better prices than average, did not maintain stock on site (shipped from warehouses or distributors) - and no longer exist. All signs of a "scam site" today. I got great service as well. So, it's getting harder to tell who is legit and this probably makes it hard for anyone trying to get into the online business for what we want.
Play safe, boys!
