There were different appliance manufacturing companies in the USSR, and consumers very clearly expressed their preferences. Different Soviet brands commanded different prices, and had different levels of demand for them.
Pricing was an issue for different reasons - some people had money that they couldn't spend, whereas other people had very little money. Food and housing were heavily subsidized but goods weren't, wages for different professions were very different (And rarely reflected the social/economic value of their work.)
It wasn't some communist paradise where everyone was equally poor. There were absolutely class and wage distinctions. An engineer building rockets was getting paid more, and had access to better stores (And priority on high-end consumer goods, that were less, or not available to the public) then one building bicycles. One way to be 'politically connected' was to work in an important industry (Specifically, defense. Being a senior manager also qualified.)
The Soviet rationing model rewarded both political parasites, and successful people[1]. A bit like 'meritocracy' works in many Western corporations, if you think about it.
The serious problems in the Soviet economy were the absolutely insane military spending, corruption, bureaucracy, theft, inconsistent accountability, and extremely conservative commandments from central management that strongly discouraged, and sometimes punished innovation and optimization.
