A listing qualifies when its vendor compare-at markdown is 5–85% and its price is at least 10% below comparable listings, or it is a tracked 3-point 30-day low that is not above that group.

Vendor list prices, market comparisons, and tracked history are different baselines. Checkout discounts are named separately.

Prices and stock can change. Check the vendor’s lab report, shipping rules, and final price before buying. TerpSeek may earn a commission from vendor links.
