Showing special offer in tiers module

Hello,
I would like to start offering subscriptions with 3 tiers. I would like to show people my standard rate in the middle tier will be 50 euro a year, but that they can now get a 20% discount. I have created the offer, and can put it in my newsletter, but can’t seem to automatically show it to people who come to the subscription tiers module through another way, for example if they are new to my site/newslettter. Do you know how I can show the offer in the menu? (I can of course make a tier with 40 euro, but I’d like to show people they are getting a discount)
