The repricer adjusts your Amazon prices automatically to win the Buy Box — safely. It never prices outside bounds you set, both anchored to your own Shopify price, so you stay margin-safe and within Amazon's expected range. The repricer is available on the paid plans.

The Buy Box repricer

Priced to stay compliant with Amazon

Amazon's Marketplace Fair Pricing Policy penalises prices that are too high (which causes listing suppression) or below cost. The repricer is built around that policy:

  • It never prices outside your floor and ceiling, both set as a percentage of your Shopify price.
  • It only lowers your price when you do not already hold the Buy Box.
  • When you already hold the Buy Box, it holds your price — there is no race to the bottom.

Repricing rules

  • Enable automatic repricing — the master switch. Off by default, so nothing changes until you turn it on.
  • Strategy — how the repricer reacts. "Beat the lowest offer" undercuts the current lowest competing offer.
  • Undercut by — how far below the lowest competing offer to price, in the marketplace currency (for example 0.01).
  • Price floor (min) — never sell below this percentage of your Shopify price. This protects your margin.
  • Price ceiling (max) — never price above this percentage of your Shopify price. 100% keeps Amazon at or below your store price and avoids Amazon's high-price suppression.
  • Run every — how often the repricer runs (in hours).

Set your rules and select Save rules.

note

The floor and ceiling are percentages of your Shopify price, not fixed amounts, so they move with your Shopify pricing automatically. A floor of 85% and a ceiling of 100% means "never below 85% of my store price, never above my store price".

Per-product overrides

As well as the store-wide rules, you can set a per-product minimum and maximum from the product's detail page, for products that need tighter or looser bounds than your default. These override the percentage rules for that product only.

Running it

  • Reprice now runs the repricer immediately across your eligible listings.
  • With automatic repricing on, it also runs on the schedule you set under Run every.
  • Refresh reloads the current status.

How it uses your data

The repricer reads the live lowest Amazon price and your Buy Box status from Product Mapping, and your Shopify price as the anchor for the floor and ceiling. Its effect on your Buy Box win rate shows up over time in Analytics.
