Just picked up a 96er of PS at Cenex in Butte, MT for $13. 99. Howe's was on sale for $8. 99 for a 96er, but I didn't see it till I was walking out the door.
Shucks, I'd have bought a couple of the Howe's just on pure speculation!
We only get to a Walmart maybe once a month - Flying J maybe once in 6 months or more - so I usually lay in a supply, as I had intended to do at the above mentioned Walmart visit...
I did manage a great buy last summer on a 2 1/2 gallon jug of PS Fuel Supplement in concentrated form - enough to treat over 3000 gallons of diesel - paid $59 for that - seems like a REAL bargain now!

That was the first and last of the concentrated PS stuff I had seen. On a side note, I usually use PS Diesel Kleen - it's the best of the PS stuff for lubricity treatment, but not much for cold weather anti-gelling protection.
So Tuesday we headed over to my Dad's in Payette, and hit low temp of right at ZERO degrees over one of the mountain passes between here and Payette. I'm still running on summer blend diesel, and the truck started running a bit rough at the low temp - checked the fuel PSI gauge - ZERO PSI! (usually 16 PSI or better)
I pulled over to check things out, suspecting a fuel system freeze up - everything looked physically OK, tried the restart and heard the 2 fuel pumps turning over, and she fired up as fuel PSI sluggishly crept back up near normal. We were nearly at the top of the grade at that point (about 5300 feet), so figured temps would start climbing as we took it easy on the downhill side. Fortunately, I was correct - and the rest of the trip was uneventful. We've been here for 2 years now in eastern Oregon - but that was the coldest temps we or the truck have been exposed to - so that was a learning experience!
Bought a few partial fillups since, using winter fuel - and also dumped in some of that PS fuel supplement concentrate - so I think we are OK down well into sub-zero temps now...
