Amika hair straightener Don't buy this straightner from a kiosk!! Internet

I was in Vegas with my mother shopping in a mall. We get stopped by a representative of Amika who showed us the 1.5 inch hairstraightner. She told us that the normal price of the straightner is 200 $ but would give it to us for 150$, and if we bought a second one, she would give it to us for 100$.
The price seemed a bit too high but we thought that since there was a lifetime warranty, this was not too bad.

When I came back at the hotel, I checked the price of the straightner on Amazon and saw that it was regularly sold for less than a hundred dollars! We were shocked and thought that we shouldn't have bought the straightners that fast.

Two days later, we were walking in downtown Las Vegas and we get stopped by another Amika rep. We didn't tell her that we had already bought our straightners and told her about Amazon's price. She directly offered to sell us TWO straightners for 170 dollars, tax included! We couldn't believe how much we were ripped off!

One advice: NEVER NEVER NEVER buy anything from kiosks without checking the price online. Read online reviews FIRST. Those kiosks rep are making so much money by fooling people
