Comparison discipline
Do not let unlike data become a trend
Price Tracker does not calculate a difference across currencies. Variable or unavailable prices remain labeled, and source roles stay explicit. Confirmed matches determine which product records belong in a comparison.
Start with a focused research set
Monitor the sellers and products that answer a specific question, then expand the set when the source coverage is useful.
