qualifier token a chosen word

tiers mode

How a quantity-break price schedule's tiers combine: graduated (each band's amount applies only to the units that fall in that band) or volume (the band the total quantity reaches sets the amount for ALL units). The discriminator that gives a tier schedule its meaning. A qualifier of the tier-price host, bound to one tier statement (so a product may carry a graduated schedule for one segment and a volume schedule for another); a filterable token from a growing vocabulary.

Tiers mode is answered with one word chosen from the tier pricing modes list — the same word shared across every product that uses it.

It is a qualifier of tier price — it has meaning only inside a tier price statement, one per statement, never on its own. It belongs with tier price to pricing — what it costs.

It is answered inside every tier price statement, not as a standalone question on a kind.
