Thanks to sparenoexpense for clarifying my misunderstanding that the DNA total listed in the offer is not just common DNA but also includes the Epic and Rare DNA.
Still feel like I got cheated as utilizing the words minimum guarantee gives the notion that you will receive more. Makes me wonder if they realize that the marketing tactics they are using in these offers make their user feel cheated and turns them off. The way these offers are presented is just not right!
Only good thing about this experience is I was given some sage advice to focus on buying coins. Thanks all.
