Yeah my prices were from singles. Most commons should only cost around 25 cents. I have only been playing this game for 4-5 months. What I did was go to the Avengers sneek and ended up getting 8-10 packs for $25. I then bought about 10 more packs over a few weeks. I only do this with new sets. With what I had I was able to build a decent avengers deck for about $10 more. It didn't have avengers assembled but worked good for a learning deck.
