Online prices are not the same everywhere. Retailers and marketplaces often show different prices, currencies, delivery options and stock depending on the visitor's country. Price monitoring proxies let you load public product pages from the market you care about, so your data matches what local shoppers see. Our 4G mobile proxies use real carrier IPs and are launching in the United States, Ukraine and Moldova.
Retailers, brands, marketplace sellers and price comparison teams use them for competitor price tracking, stock checks, catalog research and checks that resellers follow a minimum advertised price policy. Stick to public pages where the site's terms allow automated access, at a pace the site can handle. If a shop offers an official feed or API, use that first and keep proxies for public pages without one. Our guide to responsible proxy use covers the ground rules.
Decide what to track before you collect anything: price, currency, discounts, shipping cost, delivery time, stock status and product variants. Save each reading with a timestamp and the market it came from. That lets you compare over time and spot changes that matter to your pricing rules. For wider public data collection beyond retail, see our page on web scraping proxies.
A price list seen from your office is only one version. Regional pricing, taxes, shipping zones and local promotions all change what a shopper pays. A carrier IP in the right country shows those local versions. Compare like with like: check your price and a competitor's from the same market and in the same currency. The same checks confirm how your own store and marketplace listings appear to customers there. Brand teams can pair them with brand protection monitoring to find unauthorized sellers and counterfeit listings.
Change the IP on demand between independent fetches, such as a list of product pages. Keep the same IP for flows that keep state, such as selecting a delivery region or walking through a multi-step cart, and change it only when the flow ends. Our guide to proxy rotation shows both patterns.
Match the schedule to how fast prices move. A daily pass is enough for many catalogs, and fast-moving categories may justify more. Spread requests over time, add delays, cap concurrency and back off when a site slows down or returns errors. Fewer, well-timed checks give cleaner data than constant polling.
You pay per GB for price monitoring proxies, so keep each check lean: request only the product data you need and cache pages that rarely change. Start with one market and your most important products, check the data quality, then add markets. When you are ready, compare plans and per-country prices or buy mobile proxies for the markets you track. The article on web scraping at scale covers rate limits and data validation.
