Won’t buy again

I walked into Sephora looking for a lip gloss. The chick that sold me the Sephora gloss made it seem like i was buying the best gloss in existence. I tried it on at the store and i liked it. When I tried using mine at home it doesn’t even feel the same way. And I fail to see the difference between this one and a cheap one I could just buy at Walmart for a third of the price
