I've read a number of posts in the forums referencing the Ubercart Repeater module, but I can't find it anywhere to download it. I searched drupal.org and the contributions here on ubercart.org but no dice.
ETA --
Upon further searching, I discovered that the module was deprecated for Ubercart 2. Presumably, that means there is another (better) way to create a master/slave relationship between the catalogs of two sites.
What would that be, thanks?
