<human>: Well it is the summer Steam Sale online and I've been waiting for the game Payday 2 to go on super sale.  Last night it finally happened and when I went to purchase it, I saw that they also had the "Four Pack" on super sale.  I thought to myself, "why not buy that?  I bet it has all the DLC's and everything!"  I purchased it right away and started downloading.  Once it was done, I noticed that I only had the base game, none of the extras I thought were coming.  I couldn't figure out where all my other content should be and I started frantically searching the website for answers.  Well I'm not sure if it was me being high or because it was late at night, but I thought "I must just not be getting something, I'll check it again in the morning."  I woke up this morning and started talking to my roommate about it.  After talking about it, I realized what had happened.  I had bought four versions of the game hence the "Four Pack."  It was not four of the DLC packs, it was four versions of the game I'm assuming to give to friends as gifts.  So I paid four four copies of the exact same game.  Thank god I waited until it was on 80% off so I only spent $18, I feel like a moron all the same.

Can you give me the gist of the text in a nutshell?
<bot>: I bought four copies of the same game on sale instead of buying the the extra downloadable content like I thought I was for $18.*
