how to install commerce_kickstart on an environment with PHP memory_limit less than 128M? I tried the full core install aproach and got a warning that I only had 96M on php memory_limitand kickstart needs 128M. tried anyway and sure enough got a memory error at the very end of the installation. I looked around my host and I'm sure I can't change that.

How can I make this installation work?
Try the methods listed here to increase the PHP memory_limit value

If none of those work, you may need a new host for that application.
