hello i went to the torishop and found the vampire pack for 0.00 and i clicked buy it says "this item cannot be bought right now" i need to find out whats wrong .

If it says so, then it's exactly as it says. You can't buy it right now.
If you really want it, go to the market board and find an offer right here: http://forum.toribash.com/forumdisplay.php?f=64

Or, search for it in the market deals. I did it for you, already, check the prices in this link:

brotip: you'll need more than 0 toricredits to buy a Vamp Pack
