I don't think it's worth investing any money except in clraik VIP for access to programs if that is your thing. You're not going to make big bucks or anywhere enough to replace a job dealing virtual items on a pet site waning in popularity. Sure, you can make some nice extra money if you can build up a decent stockpile of items but don't expect to make bank. Do it for the fun and enjoy the bonus money you get from it, don't look at it as a new job.
