What did you already know of the material presented in the lesson?

Something that I already knew about the material presented in today's lesson was purchasing something online without consulting about it first with someone who works in the online supply store. In previous years I myself and many other people that I know have purchased items online and have gotten ripped off because we did not consult our purchase with an employee. I have been fooled with false sneaker advertisements online, sports advertisements, and music advertisement and it has taken a good amount of money out of my hands. I learned that when purchasing an item online, I must confirm my purchase with an employee that works with the online shop and getting all of my ligitiment information like when it is going to be arriving at my house, how much I have to pay, and making sure that what I am getting is not anything fake or cheap.
