I have recently taken over managing our companies Zen Cart store. We have our product in two forms DVD or VHS there is an up charge for VHS over the DVD title. This upcharge is done using the Prefix Price for the VHS attribute.

The problem is we have increased the up charge for the VHS product and I need to have the PreFix Price changed for all products. Is there a way to do this for all products at once or do I have to do this product by product?

Thanks in advance for any help.
