Disappointed

Visited Checker Hyper at the Galleria today. Saw a table that was marked "50% OFF OrNAMENTS" on the table were solar lights which I took and went to pay only to be told the price on the item was the discount price already. Confused as this is false advertising, should've said marked off already...or to that effect. The manager came and pointed out that the white stickers orices were already marked down. As a shopper how would you know. Very frustrating and misleading indeed
