Hey Y'all,
Here are all the rules for selling on Project PET. If you break any of these rules, here is what will happen. You will get 2 warnings. Then, you will be suspended from selling for a week. After that, you will be banned from selling.
Rules:

1. You may not sell anything containing or pertaining to sexual content. Most anime will be accepted (because I'm not too familiar with the content of ALL anime) unless it is labeled hentai in other places. In which case, it will be punishable.

2. Follow all the other rules in your posts.

Short and simple, I know, but this is all that's necessary that I know of.
Project PET will not be responsible in any way for your transactions. They are your responsibility. I recommend using PayPal for your transactions. Also, when you deal through PayPal, be sure to read the confirmation emails VERY clearly. I know someone who was nearly taken for almost $500 because of fraud. If you see any typos or anything that looks suspicious in the emails, go to this page and you can find out for sure.
