Over on the men’s side of the store, the sizing has become extremely limited. When I worked in retail (40 years ago) typically men’s pants were stocked in waist size 28-44 or 46, and shirts in neck sizes 14-17. Now the waist sizes are typically 30 or 32-44 and necks are 14 1/2-16 1/2. You can find larger sizes in Big and Tall shops, but I have no idea how skinny, short men can walk into any store anywhere and find something in stock.
It’s not quite the same, but if you boil frozen vegetables in saltwater for five or ten minutes, you can approximate the canned texture and flavor. This was an accidental discovery for me, so if you try it on purpose, you’d probably get better results.
The thing I haven’t been able to find for the past five years or so are frozen pie cherries (sour, not sweet). Back in the day, there were two brands available in my local stores, but first one of those disappeared, then the other could only be found in a couple of local, independent groceries, and finally, no one had them at all. I suspect this is due to fewer people baking pies. I finally just planted a tree of my own, and after two years, I’ve been able to harvest enough cherries for one (1) pie.
I live about 15 mins from a MicroCenter and it was nearly hard to get an internal DVD/BD writer from them last year. But I did get one. And it seems they have a lot more in stock now, and cheaper 
So for a minute there it was hard to get an internal DVD writer drive. I also see they have one in stock at my local Best Buy.
My wife just went around this exact bush for about 2 months. No luck anywhere, from discount grocery to snooty gourmet organic grocery. Turns out you can order them online from Wal*Mart but even they don’t carry the product in their stores.
Seems friggin’ silly to mail-order two 14 oz cans of fruit. But that’s what it takes in the modern world.
Shoelaces. In a variety of lengths, colors and materials.
I find that Target has some shoelaces, though admittedly not a big variety.
At least until recently, Dollar Tree had a fair selection of Shoe Laces.
The last time I bought a new PC I couldn’t find one with both an internal DVD reader, and a large hard drive. There were plenty with a DVD player or a hard drive larger than 256g, but not both. You’d think that people who watched DVDs on their PCs would also want to store their music library on their PC. I ended up getting one with just the large HDD and bought an external DVD player.
How darn large is the non-cloudy part of your music library? Mine comes to 40GB but all of it is cloud-stored and each song only takes up space on the PC when I actually play it.
I have had iTunes remove too many songs from my library (including things that I uploaded from my own CDs) to trust the cloud. I have everything backed up on an external drive, just in case.
(I don’t really use iTunes because of this, but they’re the ones that broke my trust.)
It is quite surprising what I cannot find in my supermarket. Corn meal (really!), flax seeds, multigrain cereals for cooking, all of which I use in the multigrain bread I make about once a week. Other markets are better, but few have all the selection they used to.
Wallet inserts.
For ID cards & photos.
It’s buy em online, or do without.
Canned pumpkin except Oct and Nov. I use to put pumpkin in my dogs food. I stocked up in Nov when it is easy to find.
Sweet potatoes. The selection from March to Aug gets very limited. I’ve gone to stores that only had a handful of shriveled up choices. I always look forward to the harvest in Sept.
My local music collection is around 4TB.
Jeebus dude, that’s a boatload of music. Not trying to be judgy, but that bespeaks a lot of time spent collecting and curating.
And/or higher quality encodes. If I ripped my CDs at the highest level of quality for my equipment, it would more than double the space on the drive. 4TB can ton of music, but at high end lossless .wav format, that’s only 50k songs.
I don’t even like that many songs.
I’ve probably never heard 50K songs in my life. Not 50K distinct songs; 50K total playings of any/all songs including all repeats.
Obviously I’m not into this stuff nearly as much as some people.
Most of the shoe stores out this way sell shoelaces in a variety of lengths, colors and materials. Except for the stretchy elastic ones which usually only come in a couple of “fun” colors.
We can’t always find dark corn syrup, except near Thanksgiving.
