I'd like to setup a website where I compare different products.
Is there a Plugin / Widget available that allows me to change / update certain Information like Price, Product Description, Manufacturer etc. in a Database / Excel format style?
e.g. I have 25 single "Product Detail" Pages and want to reduce the price for each Product / Page by 10 %.
I just don't want to update all 25 Pages, but rather update only one file.
Look forward to your replies.
