Shoecity.com review: wrong price

I wanted to purchase the pink youth Jordan shoes with the price tag on them as $19.97. I get to the register and the young lady says $55.00. I explained to her the tag says 19.97 and in so many words she says sorry. That wasn't the only shoe marked $19.97. It's not my fault as that the store choose not to change the prices on several shoes, that were on the shelf. This is horrible customer service and she should have left the register and checked.
