How to bulk increase my selling prices by 10%

[sandra4003]

Due to the recent postage increases, I need to increase my selling prices by a fixed percentage as I do not charge for postage. 

Is there a way to do this in bulk rather than go through each individual listing?

If you a business seller, go to your listings.

There should be a drop down menu.

As a private, I dont know as I dont sell on a private account but i know its different go to selling >  active.

See if there is a tick box you can select all or a drop down like above,
