I’ve noticed retailers cycle shallow promos, so I sanity-check with the 90‑day median on Keepa and only buy when current is at least about 12% under it - for example, the LG C3 55" hit $1,099 this weekend vs a $1,249 90‑day median, which lines up with pre‑quarter‑close markdowns. If you’ve found a better threshold or a tool that nails seasonal dips, I’m all ears.
