Spontaneous deals on packs - no more

Hello! I have a question about the deals that randomly come about. In the beginning I received some really great deals and the more I have played the game the less deals I was offered. Now I am never triggering a spontaneous deal to pop up. The only deals I am ever gaining access to are the ones that come about on holidays and special occasions. It would be nice that deals are still offered to veterans who devote several hours to the game each week. Offers like a buy one get one pack, or reduced price offers.
