My only complaint is sometimes the parts I need are in a warehouse far from me so shipping costs and delivery times are higher. However with these prices I can wait a little, try to plan ahead and purchase parts I will need. I had a Nissan with a bad cv joint boot. Local parts stores, that had the part, wanted $55-75. Rockauto had the whole axle for $35 and with 100,000+ miles it was a no-brainer. Later the same car needed a lower control arm ball joint and the entire arm with ball joint was less than the ball joint locally.
