Where do you all buy piercings?

I’m specifically looking for an online option.

Every time I go to a store to get a new piercing it always seems way more expensive than it needs to be, which, it is what it is. But I can never find something I want or I want one thing out of a pack of other things that I’ll never use.

I’m also very sensitive to reactive metals, so it needs to be a reputable source (i.e. not a gamble on Amazon).

Thanks piercing peoples!
