What retailers publish they charge vendors for compliance failures — 492 published fees across 24 retailers, each quoted from the retailer's own public document. Whether a given fee is enforced on a given shipment is between you and your buyer.
Try the pre-dispatch check (demo) — tick what is true of an example shipment and see which published fees it is exposed to, with the quote behind each one.
What Weis Markets changed in its published chargeback schedule — the 2018 and 2025 editions set side by side, every fee quoted from the edition it appears in.
Walmart, Target and Amazon put their vendor requirements behind supplier logins, so there is no public document to quote. Nothing here was taken from a login-gated portal.
Their fee schedules are not published anywhere, so they can only be learned from chargebacks suppliers actually receive. That may never be something we can cover — leave an email and you'll hear if it changes.
