Before anyone jumps to conclusions, i am not affiliated with these folks what so ever, just wanted to let board members in on some awsome customer service/products. I was in need for two new O2 sensors and serched around on the net, I came across this sight and decided to give them a try, for one there prices were $34 each, so what the heck. I did an online transaction, two hours later received a tracking number, two days later received both AC Delco sensors.
