One row per price seen: list, promotional and regional prices are separate rows, and channels that disagree sit side by side. Nothing is averaged or overwritten.
Activations syncs data from a warehouse or lake into business tools such as Salesforce or Braze, and on the Enterprise plan adds Audience Hub for building audience segments.[1] It is priced on monthly active rows (MAR), with a rate per row that falls as usage grows, and each new activation starts with a 14-day free trial.[1] The Free plan covers 3,500 MAR a month for activations; the Standard, Enterprise and Business Critical plans have no published per-row rate and are quoted through Fivetran's estimator or sales.[1]
