Magento is really very well structure system based on zend framework. But it is bit complicated for some people. There are loads of things which user/developer want to get the answer for. One of them is how to update product price in bulk.
So answer is very simple just make a csv file with three field store, sku, price that’s it.
now go to admin >> system >> Import and Export >> Dataflow and then click Import all Products and run the profile with this file.
