Hmmm.... I buy everything I can from Advance Auto Parts & can't remember ever getting anything that was bad, right out of the box. (Same thing goes for all other suppliers...) Mabye I'm just lucky, but they say that sometimes it's better to be lucky, rather than good! : )
Also, I have a list of discount codes for Advance if anyone is interested. They run specials all the time, but these codes (so far) work all the time, regardless. If you spend over $75 then you get free shipping. Spend less, & I usually just opt to pick up my order at one of the many local stores. The codes range from 20% off ANY order, up to 40% off depending on how much you spend. Order strategically & you can save a bundle! YMMV w/ the parts, but like I was saying I've had good luck so far.
