This afternoon we went to Herbergers, where I spent $90 on a $90 pair of shoes that cost $90. The shoes, which cost me $90, were not on sale. I went to the cashier, told her I would like to buy these shoes for $90, and was charged the full $90 retail price for the shoes.
The price of the shoes -- which was $90 -- was paid in full. I agreed to pay the whole amount of the non-negotiable price advertised for the shoes.
