Temu is just driving the social media impulse "buy buy buy you need it buy it now!!" Culture when in reality their stuff is crap, and even for the cheap prices... You probably weren't going to buy it anyway. They are really striving in being a shitty company that's bad for us and the planet.
Good video here that explains more of how they're just manipulating us to buy more: https://youtu.be/7hGD5Cz_now
TikTok and them just fuel each other to create fake fomo and it's so crappy. They target kids so hard and take advantage of them wanting to fit in, and get them to just spend money on crap they didn't need to buy anyway. Not to mention they've pushed fashion cycles to be faster to make people think that top they bought 2 months ago is useless and should be thrown out.
Some things on Temu are complete trash but some are really good for the cash. They have a HUGE range of pin badges for less than a dollar, I've seen some of the more expensive ones ($2) sold for $10+ on other marketplaces like Amazon.
