The FAQ says Starter drops from $19 to $15/mo and Pro's base from $49 to $39/mo, and that the same discount applies to additional storefronts. API Partner is $1,200/mo with a six-month minimum. Agency / Enterprise says from around $199/mo. The trial buttons say 14 days free, no card. The FAQ says nothing is charged until you pick a plan. Starter includes 50,000 API calls a month. Pro includes 25,000 API calls per storefront per month, and the page says that is 125,000 at 5 storefronts. The page says there is no overage bill. Past the allowance, calls are slowed. FBA Fee Recovery on Pro is described as claim-ready downloads at 0% commission. That is a feature on the pricing page, not a separate subscription price.
