What are spending limits? Why do you have them?
The spending limit for the NC Mall is set to a maximum of $75 in the first 30 days, $150 per month after that. This is in place primarily to reduce the impact of a fraud occurrence.

How long does it take to get my Neocash via PayPal? I purchased Neocash, but have not received it.Usually, the PayPal transaction will be completed instantly. However, there may be one or more verification issues that would cause a delay. Please be patient and do not submit another purchase request or you may end up buying twice the amount you initially intended on.
If a week has passed and your balance still has not updated please report this to
ncmall@neopets.com.
I don't know if this helps you. But maybe you can try waiting one more day??? If anything, I would send a bug report to TNT just in case this doesn't clear up in another day or two.
Good Luck!
