Disorganized

I went to Mr price cradlestone on the 20/12/2021 to buy some clothes. I found this other shoes and there was no price tag on them, I went to the till to pay and they did not find the price for the shoes I had to wait for more than 30min,went out of the store and came back, still they did not find the price for the shoes.why put something on shelves that you won't be able to sell.im very disappointed. My time was really wasted
