I discovered Temu a few months ago (advertised on the SF site!) after I accidentally clicked on it. When I saw the cheap prices, I was hooked. I made a small purchase at first, was satisfied and and have been shopping regularly since then (I try not to buy more than 25 dollars at a time. I get a lot for that amount!). The prices are extremely competitive, and shipping is free. I also noticed that several packages came from New York and New Jersey. It doesn't take that long to get here.
I usually get art supplies (paints, brushes, watercolor paper), supplies for card making (patterned paper, stamps, double-sided tape, flower stickers, etc), flashlights, tape, insulating tape, etc. These are a fraction of the cost of Amazon. I have been pleased 95% of the time. I did not do well with the few tops I ordered. They were not sized properly or made of cheap material. So I don't shop clothing, but I have been pleased with everything else.
