This module is designed to allow to you set specific shipping amounts for specific SKUs in your store. It creates a database table that keeps track of the items and shipping amounts so it doesn't modify or break core VirtueMart files or database in any way. You set the pricing you want for each SKU in the module configuration screen (From the VirtueMart Store Control Panel click Store->Shipping Module List->Configure Ship Method for the ship_product module).
The module is based on previous work of Theodore Root, CompDat.com, The code was updated to support latest PHP, VirtueMart 1.1.5 and to use VirtueMart core language tokens instead of hardcoded English text strings to be easily integrated in non-English shops. Also couple of small bugfixes where added.
