Angie needs a new dishwasher. She saw a great sale on the model she wanted and went down to her local appliance store. When she got there, the store owner said that they no longer had that dishwasher, but they would be happy to sell her a different model at a higher price.

It is false advertising.

It is creating an invalid debt.

It is preventing fair competition.

It is engaging in unfair or deceptive business practices.
