Okay, so today I bought a pair of black jeggings at american eagle. The price tag was ripped off of all of the jeans in the store. I asked the lady near the changing rooms how much they were, and she said she was pretty sure they were $40. When I went to pay for them, the woman charged me $60! There wasn't a price on the tag, there was no proof. But I remember a while back and the jeans were $49.99 regular price. When I went back to the store to get a price adjustment, the lady said they were still $60. I showed her the website which said they were on sale for $30, and she replyed that it was the american website.

I feel like I've been taken advantage of. Any suggestions?
