I've read that some Dollar General stores carry QS filters. I haven't found one yet. I did buy a Havoline oil filter a Freds here in my small community. I was actually surprised at how well it was put together. I didn't have photo capabilities when I did this a month or so ago. Nice, metal end caps that I could not separate the filter media from. Filter media looked good with more than 40 pleats (can't remember exact count). Rubber nitrile ADV. The only thing that looked, in my unprofessional opinion, a little weak was the pressure relief valve. And it was probably more than adequate. All in all, for less than $3, I'd throw one on in a heartbeat if I didn't have a stash already.
