I was 15 years old in 1989 (the year of the "revolution") so I can remember a few things about Ceausescu regime...
About ordinary commodities: from my parents memories
before early 80's, it was relatively no problem in finding basic supplies.
After that the situation got ugly: gasoline was rationed (about 20 liters/month, but you had to wait huge lines, because it wasn't available all the time), sunflower oil, sugar, flour were rationed (in my town we were lucky the bread was't rationed, but it was a very "not-tasty" bread anyway). Meat and meat-products, butter were "rara avis".
For some poor quality milk you should get up at 3-4 a.m. and join the queue...
In the last years of the regime you could have a hard time in finding toilet paper, toothpaste, light bulbs (this particular ones I remember). We took advantage of our annual trip to the seaside to buy gasoline, toothpaste and so on... And, I remember clearly, PEPSI
For a shitty colour TV you could wait for a year or more, the same thing for a shitty car.
I lived (and I still do
) next to the former "big supermarket" and I remember that we were walking in and the shelves were almost empty, just some small potatoes, some bread, vienamese shrimps and a lot of jars of beans, peas, jam.
The TV programmes were 2 hours/ day, mostly "news" and songs of worship for the great leader. Saturday and Sunday there was a longer program, we had a little bit of cartoons, some movie, you got the picture.
You could ocasionally find a good book to escape censorship (and we say the only advantage of those days was that people were at least reading something...).
Some regret those years because, they say, "we were given an apartment and a job". Yes, the communists build a lot of apartment flats, but they were -mostly, over 90%- ugly, small and very poorly built...
I remember I thought we were the stupidest nation alive because when my parents or relatives went on trips to, let's say, Poland or even USSR they returned with toys, bags inscriptioned with "Coca-Cola" (woow), sweets and tons of "good stuff" we couldn't find on our market. And those were "socialist countries" also...
