Going by the dates your launch is about now, so I'll aim at where you actually are rather than the three weeks that have gone.
One thing nobody's picked up that I think matters more than the follower question: you're selling through your own website. That quietly changes a lot of the advice above.
I run a TikTok Shop, so the bit I'd flag hardest is Saleh's affiliate suggestion. It's the best advice in this thread but commission deals through TikTok's creator affiliate programme run on TikTok Shop products. Website-only, that route isn't open to you. You're back to flat fees, or your own affiliate scheme with links that make people leave the app. That's a materially worse deal, because the commission structure is what keeps creators posting after the first video rather than banking the fee and moving on.
It cuts the other way on BusterBloodvessel's warning, though the fees, the returns, TikTok siding with the customer on damage claims that's all TikTok Shop too. On your own site, most of it doesn't apply to you. Worth separating those, because right now they're being weighed as one thing.
So the question I'd want answered before spending anything: is website-only deliberate, or just the default because that's where the site was? Every extra tap between the video and the checkout costs you people, and organic video to external site is about as many taps as it gets. Plenty of brands run both Shop for the impulse buy, site for the subscription.
On the Live plan: genuinely good fit, unboxing is native to the format. But don't let the launch one be your first. Go Live twice this week when nobody's watching, and be bad at it then. Watch time is the thing that matters and it's not a skill you want to be learning with an audience.
And I'd underline NelaKo's point on email capture harder than anything else here. Followers are rented. The list is yours.
And a last point, worth knowing before you decide the Shop question either way.
We have a TikTok Shop, and we get flagged when a video tells people to go to our website. TikTok's redirecting-traffic policy covers calls-to-action pointing away from a promoted product livestreams, videos, bios, descriptions. Once your products sit in the Shop, "link in bio, head to our site" stops being a tactic and becomes a violation.
That doesn't bind you as things stand, because you're website-only. A normal traffic or conversions campaign pointing at your own site is exactly what that ad objective is for.
But it does complicate the "run both" suggestion I made above. Opening a Shop buys you the affiliate route and in-app checkout, and it costs you some freedom to push people to your own site. For a subscription box where the model depends on getting the customer onto your billing, not TikTok's that trade-off is worth working through properly rather than assuming you can run both freely.
