Moscow is different from the rest of the country, but the food prices & prices in general have been rising quite significantly. Obviously the prices on the more expensive/complicated stuff to make, most of which is being imported — cars, phones, computers, washing machines (now forever linked to this invasion) etc. have skyrocketed, a lot of those goods have already disappeared from the shelves (big stores only rely on what they have on storages now) while companies try to set up a "parallel import" routes (legitimised contraband) or find new partners in China/India etc.
Shopping malls are really struggling since a lot of foreign brands have either suspended their activity or permanently left — IKEA, H&M, Zara, Uniqlo, adidas, Nike, McDonalds etc. And obviously you can't replace them all at once even with drastically inferior products. Cinemas have lost around 70% of their regular audience since most of the big studios don't allow their movies to be distributed in Russia anymore. The unemployment rates have, again, skyrocketed — foreign corporations are leaving, any business that was reliant on import & export have taken a huge hit, entertainment and service industry is struggling since people aren't spending on it etc.
I'm still not sure what they're going to do about aviation. They've kept all the foreign planes that were leased out to Russian companies for internal flights (since they're going to be arrested the moment they land in a non-Russian airport), but there's already a critical shortage of spare parts and details that are absolutely integral for their functionality (and it's not that easy to import them through different channels since it's such a closed market). Russian planes aren't fully Russian either — even U.S. couldn't make a proper passenger plane without any foreign details if it was suddenly cut off from the outside world... and U.S. is light years ahead of Russia in terms of aviaconstruction.
It's a bit of a paradox that those who are opposed to the war felt the first wave of the sanctions the hardest, since you're being actively cut off from the outside world (not that I support the constant moaning from that group, there are way more important issues at the moment) — something that isn't immediately felt by people who live in smaller towns/villages (where the biggest employer is always the government — schools, police, prisons, oil/gas/mining industry etc.), older people (reliant on their pensions and are unlikely to travel a lot). The rise in food prices and the exodus of huge corporations like McDonalds, IKEA, car manufacturers who have employed hundreds of thousands of people, are now being felt by them as well though. And it's only going to get worse.
