Um, I'm just going to be blatantly honest here.
The NG Store needs some work. So far I've attempted to place 2 orders. When I tried to place the first one a month ago, it literally took about 10 tries to get it to go through. I would just keep getting a blank white page when confirming on the last step.
Then I try to place another order tonight for a key-chain, and it won't go through, I get the same blank white page on the last step.
That's 2/2 with not being able to give NG my money on my first try. I might try to place the order for the key-chain again, but I might not. Nothing pisses me off more than when I try to give an online store my money and they won't take it :\ But I love NG so I'll probably try again :)
