Digital goods versus physical goods: Price raising question

[Monarch]

I can understand with physical products that each year due to change in tax and shipping costs etc that things might get more expensive.

But I sell digital goods, so how do I justify raise the price once a year?
Does anybody have any good arguments for me

Even though it's a digital good, you still have to grow as a company and you still have other costs that increase. It's normal to calculate all that and increase the price of your product. I am sure over time the quality of the product improves as well, bug fixes, tweaks, processing user feedback, giving support, etc. Those are time and money you've spent and it's reasonable to increase price.
