It’s not literally a scam, in that I’ve ordered things and they’ve arrived (in a timely fashion, actually), but the “free” stuff is pretty close to being one. The free credits or whatever are so over the top as to be eye rolling, so while they probably are officially a scam, I just couldn’t get too worked up.
Overall, it’s basically a tiny bit cheaper than AE, a tiny bit faster, but with more limited selection and they make the annoying gamification on AE look like the height of restraint and class. I found my personal line for trading time and tracking for cheap prices, and it’s between AE and Temu.
One tangential weird thing is that I’ve seen Shein, the fast fashion brand, has gone full “marketplace” and is now selling a lot of Temu like stuff that has absolutely nothing to do with clothes.
