I checked my local Walmart and they still carry PU in jugs and quarts. Everything seemed cheaper than usual. I think m1 wqs around $21 a jug and the PU was approximately $26.88 if I'm not mistaken.
I wish I had went to Walmart before I got the oil change sale at OReilly with the PP and a kn filter, but I was forced to go during a lunch break and it was the closest parts store. I didn't want to get stuck with a delco filter at Walmart sometimes all the good stuff is sold out.
Currently my Walmart only carries D+, mc, delco, ocod, fram ultra, or puro classic filters.
