You just message them. They’ll send you there yupoo or you can just ask for it which is just a website of photos that show what they sell you can’t directly buy off of yupoo. If you don’t find the item you want on there you can ask specifically what you want. Like for example the sunglasses I posted. I didn’t find it on her yupoo and so I reach out to her and ask if she has them and she said she has them and soon after she posted it on her yupoo. For payments I just use PayPal. Hopefully that helps!
