Category Price Change/Adjustment - by: Jonathan

I've looked and can't find this anywhere, so I hope I'm not re-asking a question that's already been addressed, but...

Is there anyway to adjust a category's price? I've got dozens of item in a specific category and don't want to adjust the price for each of them.

I wasn't sure if there was a way to do this (possibly via a coupon or voucher?). I don't want the customer to have to enter a code, so the coupon would have to apply automatically, and ideally, the new price would be reflected on the item page.

Thanks!
