t-shirts on instagram get me a lot, I also get ads for Temu for things that look interesting (Weird tech gadgets usually) but I refuse to use any site that forces me to do some stupid "spin the wheel for a coupon gag" every time I visit so have never actually even looked at an item on Temu.
I also get extremely well tuned ebay product ads on instagram but I don't usually buy anything through that flow (I poke around on ebay enough on my own...)
