On competitive marketplaces, the price that wins the buy box changes hour by hour. Automated repricing reacts to competitors in near real time, and that starts with reliable price data.
The data feed
A repricing engine needs fresh competitor prices across regions. Residential proxies let you pull those prices as a local shopper without getting throttled. WingProxy (wingproxy.com) offers per-GB residential from about $0.26/GB, or an unlimited plan from about $43.60/day for continuous monitoring.
Cadence vs cost
- Hourly checks on key SKUs, daily on the long tail
- Metered plan for targeted checks; flat plan once you monitor everything constantly
- Always store timestamp, region and currency
Guardrails
Price-match within policy, never scrape faster than you need, and respect each marketplace's terms. A calm, steady feed is both cheaper and safer than a burst.
FAQ
Metered or unlimited for repricing?
If you monitor continuously across many SKUs, the flat daily plan usually wins; for targeted checks, metered is cheaper.
How fresh does price data need to be?
As fresh as your buy-box competition moves. Hourly is plenty for most catalogs.
Repricing is only as good as its inputs. A steady, regional price feed keeps your engine making the right calls.
