TPM is built into the CPU of all 8th gen and ryzen 2000 series CPUs. The module is only needed for older systems.

I’m waiting for the day all these shitty delivery services come crashing down. But sadly I think there’s enough idiots out there to keep them in buisness.

That said these practices aren’t unique. Almost any place where you buy X + a service will charge a markup on the initial item + their service fee.
