I notice a few sites with ammo "on sale".
Then go to some familiar places and see the same caliber "out of stock".
That can't be anything but a huge flag that the "on sale" stuff is a complete scam. There are sites that claim to keep a record or judge the sites that scam. Many more scammers than I thought. Their common tip: Too good to be true **** and clickbait is really bad out there.
