in the last sale i had purchased R5 5600X, i got the package without the Cpu, someone opened the amd box from the bottom and removed the Cpu, i complained and got it replaced, this time i got a sealed box with the cpu inside... also i had taken a unboxing video coz of the unknown/shady seller... but amazon didn't ask for any proof, they just sent me a replacement after a few days...AMD Box came inside the amazon cardboard which was in turn inside the anti-tamper plastic pack. But the AMD Box itself looked a bit old and seemed like it was carefully opened and sealed from bottom.
P.s all the outer packaging were sealed...
