Mid-July is the reliable window. Every board and vendor tracked in this corpus took one $4-to-$18 cut between July 10 and August 7, 2026, and prices held at the reduced level through August 21 rather than rebounding.
The twelve-week price record shows a clear seasonal shape. Weekly series across Field Supply, Key Bazaar, and Deskhaus stayed flat through June, stepped down once per vendor-voltage between the weeks of July 10 and August 7, and then plateaued through the final observation on August 21.
Concrete examples anchor the pattern. The NK68 Frost fell from about $105 to $90.85 at Field Supply during the week of July 17, the NK65 Field slid to $118.94 at Key Bazaar by August 21, and the budget MF120 Bog settled 8 percent under its June average.
Restock calendars interact with the discounts. Several boards, including the KW100 Harbor and M65 Cairn, sold out in the weeks preceding their cuts and returned to inventory already repriced, meaning patient buyers capture the sale without fighting checkout timers.
A simple tracker beats prediction models at this scale. Watching one vendor feed per board and alerting on any drop larger than $4 would have caught every discount event in the corpus window, since each vendor made exactly one durable move per product.
