This is the independent record for the Home Depot listing above. It does not borrow prices, claims, or observations from another retailer.

Offered price vs. their claimed ‘was’

Home Depot · Sep 06 2026–Oct 09 2026

Offered price vs. their claimed ‘was’ TRUE −12% VS 34D. The offered price is $113 as of Oct 9 2026; the retailer claims a $129 reference. The plotted record breaks across 7 missing observation runs. The vertical price scale visibly starts at $106. Retained intraday facts: intraday low $113 · Sep 29 2026 · retained from that price-day; not the daily-last curve; intraday low $113 · Oct 7 2026 · retained from that price-day; not the daily-last curve. The 90-day rule selects its reference. This record contributes a 34-day observed span; all 27 price-days and 7 missing runs are shown. Daily tracking had not yet begun in the earlier part of the rule frame; that time is not a coverage gap. $120$140$1601$113 · LOWEST PLOTTED OFFERFULL POINT-BY-POINT RECORD27 PRICE-DAYS · 34D OBSERVED SPAN$113 · OFFERED · Oct 9$129 · THEIR CLAIMED ‘WAS’Sep 6Sep 22Oct 9 BROKEN SCALE · STARTS AT $106
