A disciplined workflow

Four gates between a price drop and a purchase order

A source price is a lead, not a buy signal. Move forward only when each gate is supported by current evidence.

  1. 01
    Discover

    Find a Canadian source-price candidate.

  2. 02
    Match

    Confirm model, variation, condition, and pack count.

  3. 03
    Validate

    Check demand, eligibility, history, and restrictions.

  4. 04
    Model

    Enter current fees and every landed cost.

Matching standard

A barcode is evidence, not proof.

Confirm brand, model, size, colour, condition, included accessories, and pack count. A UPC search can return zero, one, or several candidate listings; stop when the product evidence conflicts.
