Portrait of Marcus Reed, Data & Archive at GroceryCosts

About Marcus Reed

Marcus maintains the price archive and basket index at GroceryCosts.

Every extracted price goes through his normalization step — item key,

unit, price, valid dates — so cross-store comparison is always consistent.

He runs the Then vs Now series, pulling historical prices from the archive

to show which staples have moved and by how much. The archive is his moat:

the longer it runs, the more meaningful the comparisons.

Background in structured data and market research.
