My Napa has always been really decent with me, but I know the locations and policies might vary from store to store.
I use the ProSelect on most of the cars I maintain now because I'd rather support them than Wal-Mart. Their 1040 filters that I use for a Daewoo and Chevy are under $3 if I remember right. I only use the SuperTech on one application now -- a '99 Kia Sephia, they want over $5 for a ProSelect for it and since I'm only getting paid a certain amount, not what I pay for the parts, I just go with what's cheapest for me. Plus, the last time I was at my local Wal-Mart they got rude with me about recycling oil filters when it says they take up to 5 oil filters per visit (corporate policy I believe), and he didn't want to take them. He tried telling me the big bin outside RIGHT NEXT to the used oil bin that says "Used Oil Filters" was for their lube center only. Even though I've never had a problem recycling filters there before. Plus I've also learned that there are better alternatives out there, like the ProLine from Pep Boys, and the Napa ProSelect (depending on the application, some can be pricy like the one for the Kia/Nissan). I think next time around I'll see how much Pep Boys charges for their ProLine for his car and see if I can get away from Wal-Mart completely.
