If something is not spam but you want it out of your inbox there's a few options:
- click Unsubscribe next to the sender. This should be possible for essentially all promotional email.
- click Actions -> click Block <sender>. Messages from this address will now immediately go to trash.
- click Actions -> click Add rule from message (-> optionally change the suggested conditions) -> check Archive (or if you don't use labels click Move to) -> click Save. Messages matching the conditions will now skip your inbox.
There's not much they could do to make that easier without magically knowing what you care about and what you don't.
