AD sold me a Daytona ceramic BUT made me buy 10k in diamond too, help?

[Socal81]

I was offered a black face ceramic Daytona by my AD which is a well known Jewler BUT before selling to me they said I must “qualify” for the purchase and must also buy 10k of diamond jewelry.

First question, is this even legal? It seems very shady to me.

Second, I’m NOT a flipper I will keep this watch forever. But I’m stuck with 10k of additional jewelry I won’t use. Has anyone run into this before and what was the solution?

Is it a bad look if I return the jewelry because I legitimately don’t have any use for it?

Anyone who has run into this and who can provide feedback on a solution and what the AD dud afterwards, I greatly appreciate any feedback you can provide.
