Commerce isn't core, but hacking contrib has similar problems to hacking core (you just may have a better possibility of deciding not to update that module).

Depending on what changes you want to make, a module that works with commerce is likely the best option, and with _alter hooks, there is a good chance you can reach in an change what you want (you don't describe the types of customization you want to do).

Never hack core and roll your own modules as your modifications will be undone when/if you update.

Hi,

I am looking at customizing Drupal Commerce.  I've been a LAMP dev
for a
while however I am very new to Drupal.  I have a ton of questions.

First let me say thank you for all your help and guidance.

I am wondering the best way to proceed?  Hack the existing commerce
modules or create other modules that interact with the existing
commerce
modules?

Thanks again for all your help!!

Keith
