Check by the restrooms.
You know, piss & vinegar.
^ I’m filled with piss and vinegar! At first, I was just filled with vinegar.
Same problem here. I used to tell my wife that I think they move the Velveeta on a weekly basis. I started keeping notes on my phone on where I found it. My loving wife would roll her eyes, until, yes, UNTIL I showed her that last month it was in x aisle and now it’s in y aisle (yes, I took pictures…). She started paying attention and finally came to the same conclusion. The ONLY time it’s easy to find is around Superbowl, then it’s in every aisle, several endcaps and a pyramid or two next to the chips.
Aisle 2, top shelf on your right about half-way down.
Mine is in the refrigerated case, between the sliced package cheese and the fresh pasta. AND, the bottled horseradish is on the top (refrigerated) shelf above the cheeses.
Seriously? You’ve never had a philly cheesesteak? Dude, WTF?
HAH! Found it!!! Should have known it would be with the rest of the “fake cheese”: Kraft “Parmesan” cheese, “Cheeze Whiz”, etc. :mad:
He hasn’t had the joyous experience of standing for 1.5 hours in a line winding around Pat’s or Geno’s, so he can get to the front of the line and say, “Whiz wit”! :eek:
I’ve never understood why the really large grocery stores don’t put certain foods in more than one place: Parmesan cheese with the other cheeses and near the spaghetti sauce, Velveeta with the cheese and with the pasta, evaporated milk with the coffee and the baking stuff, Fluff with the ice cream, baking stuff and Jam/peanut butter (for the famous Fluffernutter sandwich.) Salsa with Hispanic foods and with the chips, crackers with crackers and with the soups/stews.
Sweetened condensed milk (aka Eagle brand milk) is really only used for baking/desserts, IME, so it seems ok to me to look for it there.
Grated, bottled horseradish has been something I have had to ask help to find. Finally, with guidance, found it with the cheeses.

Demand for shelf space in grocery stores is incredibly high. Last year, over 21,000 new food and beverage items were introduced in the U.S. For every new item that your grocery store carries, some other item has to get bumped from the shelf, and manufacturers almost always have to pay retailers (“slotting fee”) to get their products on the shelf.
If a grocery store shelves a particular item in more than one place (other than the “end of aisle” displays, which are usually for short-term promotions), it’d almost undoubtedly be because the manufacturer specifically paid extra slotting fees to get that product in both places. It’d be handy for consumers, but very few manufacturers would feel that they’d get enough additional sales from it to justify the extra slotting fee expense.
When we moved to the Lesser White North many years ago, we were puzzled by the local store’s lack of tortillas (and any other Mexican food). Finally found someone who knew where they were: in the gourmet section. Tortillas are gourmet food???
Used for coffee, too. I actually thought that’s where it was located in my grocery when I read one of the previous posts in this thread, but it turns out (having checked in the last day or two) it’s in the baking section. Still, given how often my grocery moves the shelves around, I’m not entirely sure that I was wrong that it was located in that section at one time.
Yet Another Example of Mysterious Grocery Store Layout.
Today at the “little” grocery store, on one side of an aisle you have: jam/jellies, peanut butter, peanuts & other snack nuts, popcorn, Brita filters and glassware, candy.
Wait, go back a bit.
Self respect.
If someone’s getting Velveeta®, one suspects this is not an issue. 
You’ve never tasted kittenblue’s Cheez Spread.
It does make reasonable fish bait, and when camping can liven up dehydrated foods.
Youse guys better not order your steaks wit out onions. Shaved rib-eye, Whiz, fried onions…hot sauce, on a fresh Amoroso roll–it doesn’t get any better than that.
Pat’s and Geno’s, not bad…but, I preferred Jim’s on South Street, although I haven’t been there for ~25 years.
