Tiktok Shop needs to be next. They openly allow sellers to advertise 1 TB SD cards for $15 each, and many more scams just like it. When you report any of the listings, you get an automated "Doesn't violate our terms." notification. I have started opening up complaints with the BBB, FTC, my state's Attorney General.
Where do you buy reliable SD cards without overpaying? At the moment it feels like I can waste a little money on AliExpress, waste more money on Amazon, or be taxed to finance the existence of some outdated brick&mortar chain...
