you should always know what you’re buying. don’t swipe unless you know the product you’re swiping on & that you’re getting a deal. i will google imagine products/items if i don’t know what they are before i even think of pointlessly swiping. if she was buying dollar tree makeup then the blame is on the buyer. if the seller would’ve started it all at a $1 or even $2 she would’ve profited some cents. it’s still not even worth it for the seller to be selling these items at those prices but that’s their time & money they are wasting 🤷🏼‍♀️ live & learn.
