- Add next_check_at column to track when each product should be checked - New products get random initial delay (0 to refresh_interval) to spread them out - Each check adds ±5 minute jitter so products naturally drift apart over time - Randomize delay between requests (2-5 seconds instead of fixed 2s) This prevents all products from being checked at the same time, reducing the risk of being rate-limited or blocked by retailers.
