I saw this hat in the window display and it had a sale tag on it for $15 so i took it and went to the check out line when the sales clerk rang me up he told me it was $29 and some change i said how, is it that much the is a tag on it that says $15 he said oh not this it it was a mistake so i asked for the manger and he said i am so i knew i wasnt going to get no were with him, so i left the store angry and about 20 minutes later i went back got his name and the corp. phone number, then i called them and they told me that they can do this it is up to the store discretion and that it wasnt a nationwide sale even though he had no idea what the hat look like or any info concerning the hat other than it was a colts hat so i told the guy that i would never go back to a lids and hung up.
