We are going to talk about the same product. Amongst many 300 yen items I found also as many 1029 yen goods as well. The tag of price card says super special price both in the price card of 300 yen and 1029 yen.
300 yen is slightly cheaper than usual, 1029 yen is really expensive. The tag of the price cards were both super special price. I laughed at them. Needless to say, 1029 yen was error.
