Cheap proxies for price monitoring
Price pages are small and change slowly, so the cost of watching a catalogue is mostly a question of how often you look.
Worked budget: about 10 GB a month of product-page traffic. On the cheap residential proxies line that comes to $39.50 at list price. This is an illustration from your own assumptions, not a measurement of any workload.
Why retail targets need better IPs
Retailers defend prices against scrapers more than almost any other kind of site. Datacenter ranges are often challenged on the first request, so a rotating residential pool or ISP addresses are the dependable starting point.
Cut the bill by looking less
Check fast-moving items often and the long tail rarely. Prefer product JSON or structured data embedded in the page to the full rendered page. Store the last result and fetch again only when the schedule says so.
A word on terms
Check the target’s terms of use and robots.txt, and keep request rates reasonable. Aggressive polling gets addresses blocked faster than anything else you can do.
