Amazon repricing

Repricing is usually framed as "what price wins the Buy Box". That framing is what produces price wars. The useful framing is two questions in order: what is the lowest price this SKU can afford, and is winning at that price worth it? A repricer that cannot answer the first question is just a machine for giving away margin quickly.

So the work is: compute floors from real fees, find out what is actually costing the Featured Offer, apply different rules to genuinely different parts of the catalog, and hand back a change-set a human approves.

Start from data, not a questionnaire

Most repricing advice opens by asking the seller for numbers the API already has. Pull them instead. It is faster, it is accurate, and it means the conversation is about decisions rather than data entry.
