As I've stated before I have dealt with Temu since they started, never had single problem
A lot of people who have never dealt with them are just repeating hearsay.
Their prices are great, free freight, but you just have to spend a certain amount.
Usually starts off at$25, mine recently went up to $35 which doesn't bother me because I'm usually spending more than that anyway.
Everything they state on their site is true, I had parcels that arrived a day or so late, not their fault it was Aust Post but they still gave me a $20 credit on my account for the four late deliveries.
If something doesn't fit, or is damaged or you're not happy with it they will credit you quickly and you usually don't need to return the product.
If you're buying clothes check the size table so you know they'll fit, read the product description of what you are buying.
I once made a purchase (not clothes) which was much smaller than I expected. My fault, if I had bothered to read the details I would have seen the size. Still they gave me an instant credit and I didn't have to return the goods
Make sure you log into their website yourself, don't click on any pop up ads because they could be scam sites.
