Bulk update prices using CSV

I have a website with over 2500 products and around 15 manufacturers.

Manufacturers send us a CSV file of their products monthly. So we could potentially have up to 15 different csv files with product data in. Is there a way to update product prices using these csv files and upload them to the site?

Hi,

Yes. I think you want to use mass actions (menu System>Mass actions).
There is a filter "import products from CSV" you can use to import the data. Ideally the CSV would have only the product_code and the price_value columns and that would update the price of the products.
