The short answer
With per-GB pricing, every byte you download and upload through the proxy counts against your plan. 1 GB might cost a few dollars on residential plans. You can use as many IPs as you like; you pay for traffic.
How to estimate your use
Multiply pages by page size. 10,000 product pages at about 2 MB each with a full browser is roughly 20 GB. Fetching just the HTML, or blocking images and video in your headless browser, can cut that by 80 percent or more. Also check whether unused GB expire at the end of the month.

Also known as
Bandwidth pricing, traffic-based pricing, pay per GB.

Editorial note: Proxy providers change their pools, features and prices often, so treat any figures here as typical ranges at the time of writing and confirm current terms with the provider before you buy.
