This module provides Feed Mappings for Ubercart items, including prices, weights (inc units) and attributes.
This comes from this Ubercart issue queue - http://drupal.org/node/457874
Thanks and credit to cedarm and wesleydv for the initial patches provided in the queue.
This module adds the ability to include attribute mappings (which are added to the product after it has been created), both for the price and weight fields.
Attributes and Options must already exist in Ubercart. Pretty obvious, but worth a mention!
Also added is the weight of the product. Please make sure that the weights unit is also included in the input file.
