This has been said before, but honestly if you want business, lower the price of the 2 chars and 2 letters. Everyone has a 2 char and wants $300-$500.
Think about it like this: If everyone has exactly $1,000,000, then $1,000,000 doesn't hold anymore value than the other guy making it somewhat less valuable.
Just bringing this food for thought to your attention.
Your example is fucking retarded.... what I believe you are trying to say is:
Now that there is a surplus of 2 letter/char kiks in the market it brings the value of them down and they won't sell for over $300. Deflation is the correct term.
