I don't think you should have to pay for squeezes, you can probably find some free if you look in the right places.  

Clyde Love, "Bridge Squeezes Complete"

I think David Bird's recent Bridge Squeezes for Everyone*  * Yes, Even You! is a great book and a little easier than Love.

In my opinion, Clyde Love's book on squeeze plays is the standard.  You should be able to find it on Amazon for a reasonable price.

 

This is a book requires study and work.  It is not a quick read.  Love does a nice job of running through simple squeezes, double sqeezes, trump squeezes and some compound squeezes. 

 

You will need to count and pay attention to all the cards played to master squeeze play.  Good luck!

In my opinion Love was the standard...until Bird's book came out this year.
