How do I buy Blue Orbs in Devil May Cry?

Ok, whenever I buy a blue orb, my “money” is deducted, but my blue orb count does not go up. And the cost for blue orbs suddenly increases.

What am I doing wrong?? :confused:

The count on your subscreen represents the number of blue orb fragments you have. Look at your life meter the next time you buy one.

Ahh… that makes sense. Thanks a bunch!
