Why I love purchase bonuses

I just want to show my purchase bonuses from referrals and why I love them so much.

Here are a few from Clicksia:
Yesterday One of your referrals purchased something, you received a bonus of $6.2500
12 Jul 2012 One of your referrals purchased something, you received a bonus of $2.5000
27 Jun 2012 One of your referrals purchased something, you received a bonus of $2.5000

Of course I had many more purchases but often only $0.2, these 3 were extra high.

Although I don't use Neobux anymore I did earn a few bonuses there as well. Sometimes up to $20 :)

So don't just look at how much you can earn from PTC section, often you can also get a small comission from sign-up section as well.
