Fantical sales scratch card demo is deceptive

When I try the demo, I often get very good AAA games (Silent Hill, Oblivion Remastered etc.) 1 time out of 3. I never get 7% discount or 1 dollar spending coupons like I honestly always get 100% of the time and I did a lot of those. I don't think the odds reflect the reality which I think is deceptive from a website like Fanatical. Please add the discounts in the demo and do the real odds.
