Unsatisfied

I am so dissapointed at ackermans palmridge not thw first complaint. I went today and wanted to buy something on the shelf when i get to the till all of a sudden the price on the item went up today now but the items were not yet priced with thr increased price.arguing back and forth because to me if a item has a certain price on it me as the customer should get it for that price as how all other stores work but no not acketmans because they cant do amyyhing they say it is comes from head office .so as a customer when i go to buy i must expect when i get to the till the item will be more expensive but the employees does not change the pricing on the items.please do better
