Just to be clear.
The scams are not the company's that are being mis-represented themselves. PSA isn't scamming anybody, but somebody is using their name and logo to create a almost too good to be true clearance sale web site. Then they are going on Facebook, using email and other social media to posts links to the scam site.
So if you see a "warehouse sale everything must go", don't click on the link but manually go to the website of the company and see if it's really true.
Scammer caught a lot of people hard with the JoAnn's going out of business sales. They advertised, for example, items at up to 90% off. And it was really good because people who put in an order got daily shipping updates. For about a week. Then the site and the updates just disappeared, as did of course their money.
Again, it's not Palmetto State Armory themselves, it's scammers using their logo and a similar web address like palmettostatearmory.online <don't go to this link>
