Have you read this person's other tweets? They seem like they're just a kid. Their most recent tweet was about how their mom is going to buy them a Japanese phone if she starts going there every other month... uh... yeah... okay. xDD
And just FYI~ I buy Ayu stuff whenever I'm financially able. I don't go all out and get every single and DVD like some people but I've got all her albums physically up to NEXT LEVEL. I bought that one digitally because I couldn't afford it last year. I haven't purchased Rock'n'Roll Circus yet either, but I will~
