It all deepens on whats going on
if theres only a few on the market the price some times changes
if there in high demand because of new cards they will go up
and some times people just go crazy and rise the price for the fun of it.
The market goes up and down on each card frequently
I'm not saying that prices don't change but a price going up2500 clintz in 2 das by the time its price was 3000 for almost 2 months is a bit strange don't you think???????
