So the points don't disappear from you're view, but when you redeem points, do you lose the ability to use them...say you used 1000 and when you saw you had 3000, does that really mean you have only 2000 to use?
Know how to count, just figuring out what goes with the Xper points still...no need to get nasty.
I think what you're asking is: when you redeem your points, yes, you lose your "redeemable points" that you have spent. However, you Xper LEVEL doesn't change just because you redeemed points. : ) Hope this helps.
