Price change?

[NerdyDiggers]

So I was having a look over my receipt history for my Spotify account and I'm showing that the past few months I have been charged 10.38 instead of the 9.99 I signed up for.

Is there some reason the legal agreement I signed got changed without me being notified?

NerdyDiggers - This is due to tax in your region. It's not down to us. We will have emailed you before the change.
