Advance Auto Parts has reduced the price of this Actron PocketScan Plus Code Reader from $81.99 to $41. When coupled with coupon code BIGUP15 the price is brought down to $26. If you've ever wondered how serious your car's "Check Engine" light was (can I make it to work today?), this tool helps diagnose possible symptoms and shows the urgency of taking the car to the repair shop. Shipping adds $8.66 (unless you choose free in-store pickup), and sales tax applies in most places, but even still this is $12 cheaper than we could find elsewhere.
