For me the best way that works was one method that was posted here in the Tut section.
Basically you do all the offers Peanut Lab has. The reward you instantly upon completion and they immediately let you know if you failed so you don't waste any time.
So when the Mega Capsule season rolls around or whenever theres a big deal for AP packages and stuff, the offers go down a lot. However, when there's not many things to buy AP with the offers go back up.
Here's what I was talking about:
The offers here are 122. However, during the dry AP periods of time they are all 299 and sometimes there are a few 399 and even 599 offers.
Just do those and get lucky. Check the Tut section for more tips.
Good Luck!
