Note though that the Ubuntu store is only for discovery, it doesn’t have any support for paid applications. It did, but this was deprecated a couple of years ago as the then Ubuntu store service started changing to accommodate snaps. Paid applications do exist but they must implement their own post-installation payment mechanism - the snap store doesn’t provide any facilities for this.
