CheapMF was a product-search service listed on iPhoneApplicationList in June 2007. The archived page linked to cheapmf.com and described searching products, reading customer reviews and comparing an offer with an Amazon purchase.
This article preserves that historical web-service identity. It does not verify that the old service still operates, and the surviving description does not establish a barcode-scanning feature.
The exact product matters
A useful comparison starts with a sufficiently precise description. A product family name may cover several capacities, sizes or revisions. Before comparing two offers, make sure they refer to the version you actually intend to buy.
If a search produces several plausible matches, use the original product information to resolve the difference. A shorter title can conceal a meaningful variation rather than simply saving space.
Reviews answer a different question
A price tells you something about an offer. A customer review may tell you something about another person’s experience with an item. Neither automatically verifies the other.
Read for details relevant to your intended use rather than treating every opinion as equally applicable. A criticism about portability, for example, may matter differently to someone buying for a fixed location.
Compare the complete offer
Before making a decision, distinguish the advertised item from the full transaction: what is included, its condition and how it will reach you. The historical listing does not provide a current comparison or a guarantee that one seller is cheapest.
CheapMF’s place in the archive is as an early attempt to put product research within reach of a phone. Restoring the page means explaining that specific workflow, without turning its old promotional name into an unsupported present-day savings claim.
