I see they've lately had some trends around food and architecture, but I assure you that traditionally, yurop is the meme community, where anything goes, while this one is more serious and less appreciative of memes.
That hasn't made economical sense for most products in quite a while. They still go, because taxes on gas and cigarettes are still lower, and I guess you can still get cheap haircuts.
don't forget the vietnamese markets that sell knock-off products. Plenty of people still buy their "branded" clothing there for a fraction of the price of an original item.
That depends. Most of the people I know (Czechia) go to Germany almost weekly for most of the essential products. Even if some prices might be the same, the quality is on a completely different level.
