If you shop well, you can get some of the same stuff sold and resold on other platforms, and I've got to say, with a few disappointing things, I've been very pleased with most of my purchases.

Temu, Aliexpress and Amazon all have the same cheap stuff on their platforms. If I see something on Amazon I always check AliExpress and 9 times of ten I find the same thing cheaper. Temu is no different.
You can definitely get good stuff for sure. The only reason I don't use Temu is because I find their ads annoying.
