Is this price inside an Amazon fee "Dead-zone"?

Some Amazon fee thresholds are cliffs: cross one and the higher rate applies to the whole price, not only the portion above it. Between that threshold and the price where contribution recovers, you charge more and keep less per unit. Referral tiers do it, and so do the fulfilment price bands. Amazon publishes cliff and marginal tiers side by side, and words them differently on the same page.
