Methodology
How the listings get here
At the moment, this is a hand-curated catalogue. Each entry on the table was added by a human: we picked the kit, copied the title and price from Amazon, normalized the attributes ourselves, and rebuilt the page. There is no scraping, no third-party feed, and no automated ingest yet. When prices move, the page is regenerated — not continuously, just whenever we run the build.
An automated pipeline using Amazon’s official Creators API is in development. Until that’s wired up, expect smaller coverage and slower price updates than the eventual goal.
Price per gigabyte
The primary sort is dollars per gigabyte of total kit capacity, computed as:
price_per_gb = list_price / (modules_per_kit × capacity_per_module_gb)
A 2×16 GB kit at $96 is therefore $3.00/GB. We use the Amazon-displayed list price for the default new buying option; used and renewed listings, when included, are labeled as such.
What we exclude
- Listings with no extractable capacity or DDR generation.
- Listings whose price is obviously wrong — an order of magnitude above the going rate for their capacity tier, almost always pricing errors or non-RAM accessories mis-shelved into the memory category.
- Out-of-stock listings.
