Where to buy books?
I recommend to buy your Perl books on https://www.abebooks.com or https://www.medimops.de. Prices can differ somewhat. So, compare!

Perl Weekly Challenge
https://github.com/manwar/perlweeklychallenge-club provides an interesting insight how programming problems are solved from different points of view (the first of the two challenges have the easiest tasks and solutions). In addition, you can learn about new functions.
