This is a bit orthogonal to the broader conversation, but you've hooked me with your predicament: Can you allow for preorders or "Expressed interest" at a new price point? (or at a hand-wavy price point to assess interest re: overhead/bulk/etc.) If tariffs come down, you can refund/credit, but for customers who wanted this, something-at-some-price may be better than nothing-at-any-price.
