So, I went to the front and picked up a pack of gum too. When the girl scanned the CD in the CD came up as 23.99.
I told her "I saw it for 15, I'm going to pay 15."
Then she told me someone must've replaced the sticker from another product because it came up to that price.
The sticker is underneath their stupid plastic guards so that would really require a leap of logic here.
I told her I wasn't going to pay for it. She asked me if I was going to pay for the gum as well. I said "no" and placed it on the counter.
I walked out, and probably won't be back for a while. I should've demanded a manager though.
