Complaint Review: Vine Vera

Walking thru the mall, second floor,I was approached by a young lady, who was selling skin care and offered me a free sample.  I took it and as I went to take it, a young man approached me with a full sized product in his hand.  He asked me to take my glasses off and he would show me what a miracle product he had to make your look younger, around the eyes.  I said no, I was in a hurry and he continued to talk and took my hand and applied the product.  I was stunned, especially when I didn't even offer my hand.  He continued to speak about the product and said he would give me a deal...and to watch my hand as the wrinkles disappeared.  Then he did said it would take 5 or 10 minutes and I said I can't wait, and he said I will give you a deal $900 for the eye cream.  I was floored. $900!! Then he goes I will give it to you for $870!!!  He goes I know you have credit cards in your wallet, come on just buy it.  I walked away and said I may be back, just to get him to leave me alone.  He said Dr Oz endorsed this product. I went on the main level and the same company was selling skin care...same exact set up.  I walked up to a young lady and pointed to the product and asked the cost.  She said $130, same EXACT product!!  Then a young man came up to me and wanted to try it on my eyes and I said no.  He goes I have a great deal for you...$179!  I was shocked again!!!  I said I was just quoted $130 by the young lady and he said she is new and doesn't know prices and I told him the cost at the other kiosis. He said they are allowed to make their own prices!!! I go at a price difference of $691.00!!!   I then walked away.  Is this even legal?  How can a mall have a business (2) that are so unfair to the public?
