It took forever for it to get back to normal here. There was limited TP available after the initial panic, but it took months to get anything decent on the shelves. I was ordering it online for a while.
48-72 hours after the initial panic my local large food store had literally more toilet paper on the shelves than I have ever seen in there before. However it was all super low quality and from brands I've never seen before or since.
It's the cheap stuff that you normally find in the bathroom at an average office building, fast food place, etc.
With the world shutting down the companies that supply those kinds of places had a warehouse full of inventory and most of their usual customers either were entirely shut or going through a lot less product.
I'll wager your grocery store called one of them up and got a few pallets to resell, creative move on their part.
Back when I used to use toilet paper, I would sometimes encounter a kind which would fall apart while I was still wiping, breaking up into a bunch of tiny "rollies" which would, as you may guess, would remain stuck to my butt. It was one of the "extra soft" brands, I think.
