Hello BITOG, I know we are in odd times right now but I typically like to order my oil online, and I was trying to order some 0w-40 through AAP because I had a speed perk plus they are (almost) always doing 20% off. So with their oil change special of $33.xx, and with my coupons and discounts it makes it very cheap for an oil change. But for some reason on their website it wouldn't work? I tried through their 'Oil Change special link' and through just adding it individually to the cart. I asked the AAP employees of course they know nothing of what happens on the internet. But, I was wondering if you guys have had this happen or if you know anyways around it? (Note: its only with 0w-40, it doesn't seem to effect other weights from what I noticed) But, I eventually settled and went in store and bought it instead of trying to order it. Thanks!
