OHLQ.com provides a complete inventory update every night, incorporating sales information from daily location records. Additionally, OHLQ has implemented Near Real-Time Data (NRTD) inventory tracking updates in all OHLQ locations. NRTD sends inventory updates to OHLQ.com every 15 minutes to provide the most accurate picture of inventory levels possible. When viewing a location’s product availability, you will see a timestamp for that location’s last inventory updates.
