Most ikea stuff has a very good price quality ratio so that's not true. It also isn't true that they don't use real wood, it depends on what you buy.
I’ve moved twice internationally in the last several years and I tried to get kind of medium quality stuff and the only thing that could compete on price quality ratio with Ikea was used higher end furniture. But it requires a lot of effort and patience to collect.
Now I love close to France and Ikea is definitely the best value for midrange. Some of the German chains are pretty good too (but still 30% more comparing similar quality).
IMO a lot of their “out of stock” is fake scarcity.
