🔔 FBA / Temu / TikTok fee-change alerts

One email, when a rate card actually changes.

Amazon changes FBA fees without much fanfare: a size tier moves, a surcharge appears, storage rates step up for peak. We re-verify the official US and EU rate cards every month, publish each month as a machine-readable snapshot, and diff the two most recent snapshots. If nothing changed, you get no email — we do not send filler.

What the last monthly diff found

Why you can trust the numbers

• Covers Amazon FBA, Temu semi-managed commission, and TikTok Shop commission tables — every figure is traced to its source dataset.
• You only receive an email when a tracked rate card actually changes. No change, no email.
• Snapshots are immutable: a month is published once; corrections are recorded, not silently overwritten.
• The data is open (CC BY 4.0) — you can check our diff against the raw JSON yourself.

Do the re-pricing now

An alert is only useful if you act on it. Run your SKUs through the fee calculator the moment a change lands.

Building this into a system?

If you need the changes inside your own ERP, repricer or seller dashboard — not in an inbox — we license the dataset and the snapshot feed directly.

Alert emails are sent from ylishi.tools. Every message carries a one-click unsubscribe link; opt-outs are honoured immediately. We never sell or share your address.
