okay i just looked at the peta site and here it is
The way it works is like this:
Step 1: Create a Street Team account and provide all the necessary info, including your mailing address.
Step 2: Log in to the Street Team and submit a report of what you did to help animals. If you need some ideas for what to include in your report, check this out.
Step 3: Since you get points for each action you take to help animals, the points will start building up in your Street Team account. The more you do for animals, the more points you get. Just be sure to keep checking in to report what you're doing to help animals. It helps us provide you with better resources and will get you some free stuff even quicker.
Step 4: Now comes the best part of getting free stuff for your hard work. Just go to our Street Team goods page and request what you want. As long as you have enough points, we'll send stuff out to you.
Step 5: Repeat (with a smile on your face).
