Nescafe Taster's Choice French Roast Instant Coffee, 7-Ounce
Hmm even buying a 3-pack at Amazon, it's more than $10/jar. Interesting. (I buy all my instant coffee and all other groceries at stores, not Amazon nor otherwise online -- mainly because I insist on choosing my own produce physically there in person, and while at the store I might as well get the other things I need.)
Just about any other brand of instant coffee is less expensive, but also tastes well, more like instant coffee and less like real coffee than the other brands I tried (I don't know if I've tried Maxwell, I know I've tried Folgers).
On refrigerators etc. Having two would be nice. My one and only conked out for good in February (after 18 years), and that was it. No refrigerator, no freezer. But living in Minnesota, there was plenty of snow on the ground, and I'd put a dishpan full in the freezer part and the equivalent of a dishpan full in the fridge part. That would last more than 24 hours.
Of course the freezer wasn't really a freezer, but it did keep it at around 34-36 deg F, so it was kind of a colder cold than the regular fridge which ended up at more like 40 deg.
Oh, stuff that really needed to stay frozen, I put that outside. I experienced some thawing in some day times, but I didn't have that much and made it a priority to eat that first.
I lived like that for about 3 weeks I think it was. Not much of a hardship but more like an adventure that got tiresome after awhile.
